NDepend Report

Dependency Graph

This diagram represents the Graph of Dependencies beetween the .NET assemblies of your application.
This static diagram can be useful but it is just a coarse view of your application architecture.
It is recommended to use the NDepend interactive dependency Graph and interactive Dependency Matrix for an in-depth exploration of the actual architecture of your code.

Online documentation:

Dependency Matrix

This diagram represents the DSM (Dependency Structure Matrix) beetween the .NET assemblies of your application.
The Dependency Matrix is a compact way to represent and navigate across dependencies between components.
The number on cells of the Dependency Matrix included in the report, represent the number of types involved in the coupling
It is recommended to use the NDepend interactive dependency Graph and interactive Dependency Matrix for an in-depth exploration of the actual architecture of your code.

Visualizing Code Metrics through Treemaping

In this Metric View, the code base is represented through a Treemap.
Treemapping is a method for displaying tree-structured data by using nested rectangles.
In the present treemap, each rectangle represents a method and the area of a rectangle is proportional to the number of lines of code of the corresponding method.

With the Online documentation, understand how Treemaping can help you see patterns in your code base, that would be hard to spot with other ways.

Visualizing Code Metrics with Treemap

Abstractness versus Instability Diagram

The Abstractness versus Instability Diagram helps to detect which assemblies are potentially painful to maintain (i.e concrete and stable) and which assemblies are potentially useless (i.e abstract and instable).

Abstractness: If an assembly contains many abstract types (i.e interfaces and abstract classes) and few concrete types, it is considered as abstract.
Stability: An assembly is considered stable if its types are used by a lot of types from other assemblies. In this context stable means painful to modify.

Definitions of related Code Metrics

For beginners: Where to start

Search for unwanted dependencies.
Look for complex methods listed through the standard Rule Quick Summary of methods to refactor.
Inspect other standard Rules that were violated.
See how standard Rules are written and customize some Rules to your needs.
Look at Code Metrics definitions to see how Code Metrics can help increase code quality.
Use the Code Diff feature to review code changes (pro edition only).
Import test coverage data to assess possible improvements in your testing strategy (pro edition only).

Code queries and rules results are truncated to list a maximum of 100 code elements in this report

It is recommended to use the NDepend interactive UI capabilities to browse a large list of code elements matched.
To enable or disable this setting, there is a tickbox labelled Don't show more than 100 matched items for a Rule violated in the NDepend Project Properties panel > Report tab > Avoid too big report for large code base section
This setting is enabled by default to avoid to have too large reports when analyzing large code bases.

Does this report gets too large?

There is a setting enabled by default to avoid to have too large reports when analyzing large code bases.
To enable or disable this setting, there is a tickbox labelled Don't show more than 100 matched items for a Rule violated in the NDepend Project Properties panel > Report tab > Avoid too big report for large code base section
It is recommended to use the NDepend interactive UI capabilities to browse a large list of code elements matched.

The list contains only code elements refactored or added since the baseline for comparison.

This is because the setting Recent Violations Only is enabled.
This setting reduces the violations set of code rules violated, to match only code elements refactored or added since the baseline for comparison.
Typically, when running code rules on an existing code base, thousands of violations are shown. It is not practicable to stop the development for days or weeks to fix all violations. Focusing on fixing recent violations only, represents a convenient way to prioritize violations, and fix the most relevant ones without stopping the development.
To enable or disable the setting Recent Violations Only there is a tick box labelled Recent Violations Only on the NDepend Dashboard panel > Code Rules

The setting Recent Violations Only is enabled

This setting reduces the violations set of code rules violated, to match only code elements refactored or added since the baseline for comparison.
Typically, when running code rules on an existing code base, thousands of violations are shown. It is not practicable to stop the development for days or weeks to fix all violations. Focusing on fixing recent violations only, represents a convenient way to prioritize violations, and fix the most relevant ones without stopping the development.
To disable the setting Recent Violations Only there is a tick box labelled Recent Violations Only on the NDepend Dashboard panel > Code Rules

Why should I enable the setting Recent Violations Only ?

The setting Recent Violations Only reduces the violations set of code rules violated, to match only code elements refactored or added since the baseline for comparison.
Typically, when running code rules on an existing code base, thousands of violations are shown. It is not practicable to stop the development for days or weeks to fix all violations. Focusing on fixing recent violations only, represents a convenient way to prioritize violations, and fix the most relevant ones without stopping the development.
To enable the setting Recent Violations Only there is a tick box labelled Recent Violations Only on the NDepend Dashboard panel > Code Rules

Quick Tips

In addition to the NDepend report, use the interactive UI through the standalone executable VisualNDepend.exe, or through the Visual Studio NDepend Addin.
With the interactive UI, browse more detailed data and have Rules checking updated each time the code is modified and recompiled.
The analysis execution and the report options are configurable through the interactive UI, in the panel Project Properties.
Plain HTML report (single HTML page, no javascript, no menu) is also available.
Full NDepend documentation is available on the NDepend website under the Documentation menu.

Critical Rule warning: Types too big - critical

• Rule Description:

This rule matches types with more than 500 lines of code.

Types where NbLinesOfCode > 500 are extremely complex to develop and maintain. See the definition of the NbLinesOfCode metric here http://www.ndepend.com/docs/code-metrics#NbLinesOfCode

Maybe you are facing the God Class phenomenon: A God Class is a class that controls way too many other classes in the system and has grown beyond all logic to become The Class That Does Everything.

In average, a line of code is compiled to around 6 IL instructions. This is why the code metric NbILInstructions is used here, in case the code metric NbLinesOfCode is un-available because of missing assemblies corresponding PDB files. See the definition of the NbILInstructions metric here http://www.ndepend.com/docs/code-metrics#NbILInstructions

• How to Fix Violations:

Types with many lines of code should be split in a group of smaller types.

To refactor a God Class you'll need patience, and you might even need to recreate everything from scratch. Here are a few advices:

• Think before pulling out methods: on what data does this method operate? What responsibility does it have?

• Try to maintain the interface of the god class at first and delegate calls to the new extracted classes. In the end the god class should be a pure facade without own logic. Then you can keep it for convenience or throw it away and start to use the new classes only.

• Unit Tests can help: write tests for each method before extracting it to ensure you don't break functionality.

Critical Rule warning: Methods too complex - critical

• Rule Description:

This rule matches methods where CyclomaticComplexity > 30 or ILCyclomaticComplexity > 60 or ILNestingDepth > 6. Such method is typically hard to understand and maintain.

Maybe you are facing the God Method phenomenon. A "God Method" is a method that does way too many processes in the system and has grown beyond all logic to become The Method That Does Everything. When need for new processes increases suddenly some programmers realize: why should I create a new method for each processe if I can only add an if.

See the definition of the CyclomaticComplexity metric here: http://www.ndepend.com/docs/code-metrics#CC

See the definition of the ILCyclomaticComplexity metric here: http://www.ndepend.com/docs/code-metrics#ILCC

See the definition of the ILNestingDepth metric here: http://www.ndepend.com/docs/code-metrics#ILNestingDepth

• How to Fix Violations:

A large and complex method should be split in smaller methods, or even one or several classes can be created for that.

During this process it is important to question the scope of each variable local to the method. This can be an indication if such local variable will become an instance field of the newly created class(es).

Large switch…case structures might be refactored through the help of a set of types that implement a common interface, the interface polymorphism playing the role of the switch cases tests.

Unit Tests can help: write tests for each method before extracting it to ensure you don't break functionality.

Critical Rule warning: Methods with too many parameters - critical

• Rule Description:

This rule matches methods with more than 8 parameters. Such method is painful to call and might degrade performance. See the definition of the NbParameters metric here: http://www.ndepend.com/docs/code-metrics#NbParameters

• How to Fix Violations:

More properties/fields can be added to the declaring type to handle numerous states. An alternative is to provide a class or a structure dedicated to handle arguments passing. For example see the class System.Diagnostics.ProcessStartInfo and the method System.Diagnostics.Process.Start(ProcessStartInfo).

Rule warning: Quick summary of methods to refactor

• Rule Description:

Methods matched by this rule somehow violate one or several basic quality principles, whether it is too large (too many lines of code), too complex (too many if, switch case, loops…) has too many variables, too many parameters or has too many overloads.

• How to Fix Violations:

To refactor such method and increase code quality and maintainability, certainly you'll have to split the method into several smaller methods or even create one or several classes to implement the logic.

During this process it is important to question the scope of each variable local to the method. This can be an indication if such local variable will become an instance field of the newly created class(es).

Large switch…case structures might be refactored through the help of a set of types that implement a common interface, the interface polymorphism playing the role of the switch cases tests.

Unit Tests can help: write tests for each method before extracting it to ensure you don't break functionality.

Rule warning: Methods too big

• Rule Description:

This rule matches methods where NbLinesOfCode > 30 or (commented per default) NbILInstructions > 200. Such method can be hard to understand and maintain.

However rules like Methods too complex or Methods with too many variables might be more relevant to detect painful to maintain methods, because complexity is more related to numbers of if, switch case, loops… than to just number of lines.

See the definition of the NbLinesOfCode metric here http://www.ndepend.com/docs/code-metrics#NbLinesOfCode

• How to Fix Violations:

Usually too big methods should be split in smaller methods.

But long methods with no branch conditions, that typically initialize some data, are not necessarily a problem to maintain nor to test, and might not need refactoring.

Rule warning: Methods too complex

• Rule Description:

This rule matches methods where CyclomaticComplexity > 20 or ILCyclomaticComplexity > 40 or ILNestingDepth > 4. Such method is typically hard to understand and maintain.

See the definition of the CyclomaticComplexity metric here: http://www.ndepend.com/docs/code-metrics#CC

See the definition of the ILCyclomaticComplexity metric here: http://www.ndepend.com/docs/code-metrics#ILCC

See the definition of the ILNestingDepth metric here: http://www.ndepend.com/docs/code-metrics#ILNestingDepth

• How to Fix Violations:

A large and complex method should be split in smaller methods, or even one or several classes can be created for that.

During this process it is important to question the scope of each variable local to the method. This can be an indication if such local variable will become an instance field of the newly created class(es).

Large switch…case structures might be refactored through the help of a set of types that implement a common interface, the interface polymorphism playing the role of the switch cases tests.

Unit Tests can help: write tests for each method before extracting it to ensure you don't break functionality.

Rule warning: Methods potentially poorly commented

• Rule Description:

This rule matches methods with less than 20% of comment lines and that have at least 20 lines of code. Such method might need to be more commented.

See the definitions of the Comments metric here: http://www.ndepend.com/docs/code-metrics#PercentageComment http://www.ndepend.com/docs/code-metrics#NbLinesOfComment

• How to Fix Violations:

Typically add more comment. But code commenting is subject to controversy. While poorly written and designed code would needs a lot of comment to be understood, clean code doesn't need that much comment, especially if variables and methods are properly named and convey enough information. Unit-Test code can also play the role of code commenting.

However, even when writing clean and well-tested code, one will have to write hacks at a point, usually to circumvent some API limitations or bugs. A hack is a non-trivial piece of code, that doesn't make sense at first glance, and that took time and web research to be found. In such situation comments must absolutely be used to express the intention, the need for the hacks and the source where the solution has been found.

Rule warning: Methods with too many parameters

• Rule Description:

This rule matches methods with more than 5 parameters. Such method might be painful to call and might degrade performance. See the definition of the NbParameters metric here: http://www.ndepend.com/docs/code-metrics#NbParameters

• How to Fix Violations:

More properties/fields can be added to the declaring type to handle numerous states. An alternative is to provide a class or a structure dedicated to handle arguments passing. For example see the class System.Diagnostics.ProcessStartInfo and the method System.Diagnostics.Process.Start(ProcessStartInfo)).

Rule warning: Methods with too many local variables

• Rule Description:

This rule matches methods with more than 15 variables.

Methods where NbVariables > 8 are hard to understand and maintain. Methods where NbVariables > 15 are extremely complex and must be refactored.

See the definition of the Nbvariables metric here: http://www.ndepend.com/docs/code-metrics#Nbvariables

• How to Fix Violations:

To refactor such method and increase code quality and maintainability, certainly you'll have to split the method into several smaller methods or even create one or several classes to implement the logic.

During this process it is important to question the scope of each variable local to the method. This can be an indication if such local variable will become an instance field of the newly created class(es).

Rule warning: Methods with too many overloads

• Rule Description:

Method overloading is the ability to create multiple methods of the same name with different implementations, and various set of parameters.

This rule matches sets of method with more than 6 overloads.

Such method set might be a problem to maintain and provokes higher coupling than necessary.

See the definition of the NbOverloads metric here http://www.ndepend.com/docs/code-metrics#NbOverloads

• How to Fix Violations:

Typically the too many overloads phenomenon appears when an algorithm takes a various set of in-parameters. Each overload is presented as a facility to provide a various set of in-parameters. In such situation, the C# and VB.NET language feature named Named and Optional arguments should be used.

The too many overloads phenomenon can also be a consequence of the usage of the visitor design pattern http://en.wikipedia.org/wiki/Visitor_pattern since a method named Visit() must be provided for each sub type. In such situation there is no need for fix.

Rule warning: Types with too many methods

• Rule Description:

This rule matches types with more than 20 methods. Such type might be hard to understand and maintain.

Notice that methods like constructors or property and event accessors are not taken account.

Having many methods for a type might be a symptom of too many responsibilities implemented.

Maybe you are facing the God Class phenomenon: A God Class is a class that controls way too many other classes in the system and has grown beyond all logic to become The Class That Does Everything.

• How to Fix Violations:

To refactor such type and increase code quality and maintainability, certainly you'll have to split the type into several smaller types that together, implement the same logic.

To refactor a God Class you'll need patience, and you might even need to recreate everything from scratch. Here are a few advices:

• Think before pulling out methods: What responsibility does it have? Can you isolate some subsets of methods that operate on the same subsets of fields?

• Try to maintain the interface of the god class at first and delegate calls to the new extracted classes. In the end the god class should be a pure facade without own logic. Then you can keep it for convenience or throw it away and start to use the new classes only.

• Unit Tests can help: write tests for each method before extracting it to ensure you don't break functionality.

Rule warning: Types with poor cohesion

• Rule Description:

This rule is based on the LCOM code metric, LCOM stands for Lack Of Cohesion of Methods. See the definition of the LCOM metric here http://www.ndepend.com/docs/code-metrics#LCOM

The LCOM metric measures the fact that most methods are using most fields. A class is considered utterly cohesive (which is good) if all its methods use all its instance fields.

Only types with enough methods and fields are taken account to avoid bias. The LCOM takes its values in the range [0-1].

This rule matches types with LCOM higher than 0.8. Such value generally pinpoints a poorly cohesive class.

There are several LCOM metrics. The LCOM HS (HS stands for Henderson-Sellers) takes its values in the range [0-2]. A LCOM HS value higher than 1 should be considered alarming.

• How to Fix Violations:

To refactor a poorly cohesive type and increase code quality and maintainability, certainly you'll have to split the type into several smaller and more cohesive types that together, implement the same logic.

Rule warning: Class shouldn't be too deep in inheritance tree

• Rule Description:

This rule warns about classes having 3 or more base classes. Notice that third-party base classes are not counted because this rule is about your code design, not third-party libraries consumed design.

In theory, there is nothing wrong having a long inheritance chain, if the modelization has been well thought out, if each base class is a well-designed refinement of the domain.

In practice, modeling properly a domain demands a lot of effort and experience and more often than not, a long inheritance chain is a sign of confused design, that will be hard to work with and maintain.

• How to Fix Violations:

In Object-Oriented Programming, a well-known motto is Favor Composition over Inheritance.

This is because inheritance comes with pitfalls. In general, the implementation of a derived class is very bound up with the base class implementation. Also a base class exposes implementation details to its derived classes, that's why it's often said that inheritance breaks encapsulation.

On the other hands, Composition favors binding with interfaces over binding with implementations. Hence, not only the encapsulation is preserved, but the design is clearer, because interfaces make it explicit and less coupled.

Hence, to break a long inheritance chain, Composition is often a powerful way to enhance the design of the refactored underlying logic.

Rule warning: Class with no descendant should be sealed if possible

• Rule Description:

If a non-static class isn't declared with the keyword sealed, it means that it can be subclassed everywhere the non-sealed class is visible.

Making a class a base class requires significant design effort. Subclassing a non-sealed class, not initially designed to be subclassed, will lead to unanticipated design issue.

Most classes are non-sealed because developers don't care about the keyword sealed, not because the primary intention was to write a class that can be subclassed.

There are minor performance gain in declaring a class as sealed. But the real benefit of doing so, is actually to express the intention: this class has not be designed to be a base class, hence it is not allowed to subclass it.

Notice that by default this rule matches also public class. If you are developing a framework with classes that are intended to be subclassed by your clients, just uncomment the line && !t.IsPublic.

• How to Fix Violations:

For each matched class, take the time to assess if it is really meant to be subclassed. Certainly most matched class will end up being declared as sealed.

Rule warning: Overrides of Method() should call base.Method()

• Rule Description:

Typically overrides of a base method, should refine or complete the behavior of the base method. If the base method is not called, the base behavior is not refined but it is replaced.

Violations of this rule are a sign of design flaw, especially if the actual design provides valid reasons that advocates that the base behavior must be replaced and not refined.

• How to Fix Violations:

You should investigate if inheritance is the right choice to bind the base class implementation with the derived classes implementations. Does presenting the method with polymorphic behavior through an interface, would be a better design choice?

In such situation, often using the design pattern template method http://en.wikipedia.org/wiki/Template_method_pattern might help improving the design.

Rule warning: A stateless class or structure might be turned into a static type

• Rule Description:

This rule matches classes and structures that are not static, nor generic, that doesn't have any instance fields, that doesn't implement any interface nor has a base class (different than System.Object).

Such class or structure is a stateless collection of pure functions, that doesn't act on any this object data. Such collection of pure functions is better hosted in a static class. Doing so simplifies the client code that doesn't have to create an object anymore to invoke the pure functions.

• How to Fix Violations:

Declare all methods as static and transform the class or structure into a static class.

Rule warning: Non-static classes should be instantiated or turned to static

• Rule Description:

If the constructors of a class are never called, the class is never instantiated, and should be defined as a static class.

However this rule doesn't match instantiation through reflection. As a consequence, plug-in root classes, instantiated through reflection via IoC frameworks, can be false positives for this rule.

Notice that by default this rule matches also public class. If you are developing a framework with classes that are intended to be instantiated by your clients, just uncomment the line !t.IsPublic.

• How to Fix Violations:

First it is important to investigate why the class is never instantiated. If the reason is the class hosts only static methods then the class can be safely declared as static.

Others reasons like, the class is meant to be instantiated via reflection, or is meant to be instantiated only by client code should lead to adapt this rule code to avoid these matches.

Rule warning: Methods should be declared static if possible

• Rule Description:

When an instance method can be safely declared as static you should declare it as static.

Whenever you write a method, you fulfill a contract in a given scope. The narrower the scope is, the smaller the chance is that you write a bug.

When a method is static, you can't access non-static members; hence, your scope is narrower. So, if you don't need and will never need (even in subclasses) instance fields to fulfill your contract, why give access to these fields to your method? Declaring the method static in this case will let the compiler check that you don't use members that you do not intend to use.

Declaring a method as static if possible is also good practice because clients can tell from the method signature that calling the method can't alter the object's state.

Doing so, is also a micro performance optimization, since a static method is a bit cheaper to invoke than an instance method, because the this reference* doesn't need anymore to be passed.

Notice that if a matched method is a handler, bound to an event through code generated by a designer, declaring it as static might break the designer generated code, if the generated code use the this invocation syntax, (like this.Method()).

• How to Fix Violations:

Declare matched methods as static.

Since such method doesn't use any instance fields and methods of its type and base-types, you should consider if it makes sense, to move such a method to a static utility class.

Rule warning: Constructor should not call a virtual method

• Rule Description:

This rule matches constructors of a non-sealed class that call one or several virtual methods.

When an object written in C# is constructed, what happens is that constructors run in order from the base class to the most derived class.

Also objects do not change type as they are constructed, but start out as the most derived type, with the method table being for the most derived type. This means that virtual method calls always run on the most derived type, even when calls are made from the constructor.

When you combine these two facts you are left with the problem that if you make a virtual method call in a constructor, and it is not the most derived type in its inheritance hierarchy, then it will be called on a class whose constructor has not been run, and therefore may not be in a suitable state to have that method called.

Hence this situation makes the class fragile to derive from.

• How to Fix Violations:

Violations reported can be solved by re-designing object initialisation or by declaring the parent class as sealed, if possible.

Rule warning: Avoid the Singleton pattern

• Rule Description:

The singleton pattern consists in enforcing that a class has just a single instance: http://en.wikipedia.org/wiki/Singleton_pattern At first glance, this pattern looks appealing, it is simple to implement, it adresses a common situation, and as a consequence it is widely used.

However, we discourage you from using singleton classes because experience shows that singleton often results in less testable and less maintainable code. Singleton is by-design, not testable. Each unit test should use their own objects while singleton forces multiple unit-tests to use the same instance object.

Also the singleton static GetInstance() method allows magic access to that single object and its state from wherever developers want! This potentially attractive facility unfortunatly ends up into unorganized/messy code that will require effort to be refactored.

More details available in these discussions: http://codebetter.com/patricksmacchia/2011/05/04/back-to-basics-usage-of-static-members/ http://adamschepis.com/blog/2011/05/02/im-adam-and-im-a-recovering-singleton-addict/

• How to Fix Violations:

This rule matches the classic syntax of singletons, where one static field hold the single instance of the parent class. We underline that the problem is this particular syntax, that plays against testability. The problem is not the fact that a single instance of the class lives at runtime.

Hence to fix matches fo this rule, creates the single instance at the startup of the program, and pass it to all classes and methods that need to access it.

If multiple singletons are identified, they actually form together a program execution context. Such context can be unified in a unique singleton context. Doing so will make it easier to propagate the context across the various program units.

Rule warning: Avoid empty interfaces

• Rule Description:

Interfaces define members that provide a behavior or usage contract. The functionality that is described by the interface can be adopted by any type, regardless of where the type appears in the inheritance hierarchy. A type implements an interface by providing implementations for the members of the interface. An empty interface does not define any members. Therefore, it does not define a contract that can be implemented.

If your design includes empty interfaces that types are expected to implement, you are probably using an interface as a marker or a way to identify a group of types. If this identification will occur at run time, the correct way to accomplish this is to use a custom attribute. Use the presence or absence of the attribute, or the properties of the attribute, to identify the target types. If the identification must occur at compile time, then it is acceptable to use an empty interface.

• How to Fix Violations:

Remove the interface or add members to it. If the empty interface is being used to label a set of types, replace the interface with a custom attribute.

Rule warning: Avoid custom delegates

• Rule Description:

Generic delegates sould be preferred over custom delegates. Generic delegates are:

• Action<…> to represent any method with void return type.

• Func<…> to represent any method with a return type. The last generic argument is the return type of the prototyped methods.

• Predicate<T> to represent any method that takes an instance of T and that returns a boolean.

• Expression<…> that represents function definitions that can be compiled and subsequently invoked at runtime but can also be serialized and passed to remote processes.

Thanks to generic delegates, not only the code using these custom delegates will become clearer, but you'll be relieved from the maintenance of these delegate types.

Notice that delegates that are consumed by DllImport extern methods must not be converted, else this could provoke marshalling issues.

• How to Fix Violations:

Remove custom delegates and replace them with generic delegates shown in the replaceWith column.

Rule warning: Types with disposable instance fields must be disposable

• Rule Description:

This rule warns when a class declares and implements an instance field that is a System.IDisposable type and the class does not implement IDisposable.

A class implements the IDisposable interface to dispose of unmanaged resources that it owns. An instance field that is an IDisposable type indicates that the field owns an unmanaged resource. A class that declares an IDisposable field indirectly owns an unmanaged resource and should implement the IDisposable interface. If the class does not directly own any unmanaged resources, it should not implement a finalizer.

• How to Fix Violations:

To fix a violation of this rule, implement IDisposable and from the IDisposable.Dispose() method call the Dispose() method of the field(s).

Rule warning: Classes that are candidate to be turned into structures

• Rule Description:

Int32, Double, Char or Boolean are structures and not classes. Structure are particularly suited to implement lightweight values. Hence a class is candidate to be turned into a structure when its instances are lightweight values.

This is a matter of performance. It is expected that a program works with plenty of short lived lightweight values. In such situation, the advantage of using struct instead of class, (in other words, the advantage of using values instead of objects), is that values are not managed by the garbage collector. This means that values are cheaper to deal with.

This rule matches classes that looks like being lightweight values. The characterization of such class is:

• Its instances have a small memory footprint (at most 16 bytes)

• Its instances have a memory footprint greater than zero (i.e the class has at least one instance field).

• It implements no interfaces.

• It has no derived classes.

• It derives directly from System.Object.

This rule doesn't take account if instances of matched classes are numerous short-lived objects. These criterions are just indications. Only you can decide if it is performance wise to transform a class into a structure.

A related case-study of using class or struct for Tuple<…> generic types can be found here: http://stackoverflow.com/questions/2410710/why-is-the-new-tuple-type-in-net-4-0-a-reference-type-class-and-not-a-value-t

• How to Fix Violations:

Just use the keyword struct instead of the keyword class.

CAUTION: Before applying this rule, make sure to understand the deep implications of transforming a class into a structure. http://msdn.microsoft.com/en-us/library/aa664471(v=vs.71).aspx

Rule warning: Avoid namespaces with few types

• Rule Description:

This rule warns about namespaces other than the global namespace that contain less than five types.

Make sure that each of your namespaces has a logical organization and that a valid reason exists to put types in a sparsely populated namespace.

Namespaces should contain types that are used together in most scenarios. When their applications are mutually exclusive, types should be located in separate namespaces. For example, the System.Web.UI namespace contains types that are used in Web applications, and the System.Windows.Forms namespace contains types that are used in Windows-based applications. Even though both namespaces have types that control aspects of the user interface, these types are not designed for use in the same application. Therefore, they are located in separate namespaces.

Careful namespace organization can also be helpful because it increases the discoverability of a feature. By examining the namespace hierarchy, library consumers should be able to locate the types that implement a feature.

• How to Fix Violations:

To fix a violation of this rule, try to combine namespaces that contain just a few types into a single namespace.

Rule warning: Nested types should not be visible

• Rule Description:

This rule warns about nested types not declared as private.

A nested type is a type declared within the scope of another type. Nested types are useful for encapsulating private implementation details of the containing type. Used for this purpose, nested types should not be externally visible.

Do not use externally visible nested types for logical grouping or to avoid name collisions; instead use namespaces.

Nested types include the notion of member accessibility, which some programmers do not understand clearly.

Protected types can be used in subclasses and nested types in advanced customization scenarios.

• How to Fix Violations:

If you do not intend the nested type to be externally visible, change the type's accessibility.

Otherwise, remove the nested type from its parent and make it non-nested.

If the purpose of the nesting is to group some nested types, use a namespace to create the hierarchy instead.

Rule warning: Instances size shouldn't be too big

• Rule Description:

Types where SizeOfInst > 64 might degrade performance if many instances are created at runtime. They can also be hard to maintain.

Notice that a class with a large SizeOfInst value doesn't necessarily have a lot of instance fields. It might derive from a class with a large SizeOfInst value.

See the definition of the SizeOfInst metric here http://www.ndepend.com/docs/code-metrics#SizeOfInst

• How to Fix Violations:

A type with a large SizeOInst value hold directly a lot of data. Typically, you can group this data into smaller types that can then be composed.

Rule warning: Don't use obsolete types, methods or fields

• Rule Description:

The attribute System.ObsoleteAttribute is used to tag types, methods or fields of an API that clients shouldn't use because these code elements will be removed sooner or later.

This rule warns about methods that use a type, a method or a field, tagged with System.ObsoleteAttribute.

• How to Fix Violations:

Typically when a code element is tagged with System.ObsoleteAttribute, a workaround message is provided to clients.

This workaround message will tell you what to do to avoid using the obsolete code element.

Rule warning: Don't forget to implement methods that throw NotImplementedException

• Rule Description:

The exception NotImplementedException is used to declare a method stub that can be invoked, and defer the development of the method implementation.

This exception is especially useful when doing TDD (Test Driven Development) when tests are written first. This way tests fail until the implementation is written.

Hence using NotImplementedException is a temporary facility, and before releasing, will come a time when this exception shouldn't be used anywhere in code.

This rule warns about method still using NotImplementedException.

• How to Fix Violations:

Investigate first why NotImplementedException is still used. Either the method must be implemented, or the method stub is not used and can be safely removed.

Rule warning: Override equals and operator equals on value types

• Rule Description:

For value types, the inherited implementation of Equals() uses the Reflection library, and compares the contents of all fields. Reflection is computationally expensive, and comparing every field for equality might be unnecessary.

If you expect users to compare or sort instances, or use them as hash table keys, your value type should implement Equals(). In C# and VB.NET, you should also provide an implementation of the equality and inequality operators.

• How to Fix Violations:

To fix a violation of this rule, provide an implementation of Equals() and implement the equality and inequality operators.

Critical Rule warning: Avoid namespaces mutually dependent

• Rule Description:

This rule lists pair of namespace mutually dependent.

The pair { first, second } is formatted to show first namespace shouldn't use the second namespace. The first/second order is inferred from the number of types used by each other. The first namespace is using fewer types of the second. In general this indicates that the first namespace should be at a lower-level in the architecture than the second.

Following this rule is useful to avoid namespaces dependency cycles. This will get the code architecture close to a layered architecture, where low-level code is not allowed to use high-level code.

In other words, abiding by this rule will help significantly getting rid of what is often called spagetthi code: Entangled code that is not properly layered and structured.

More on this in our white books relative to partitioning code. http://www.ndepend.com/docs/white-books

• How to Fix Violations:

Refactor the code to make sure that the first namespace doesn't use the second namespace. To get started, first explore the coupling between two namespaces mutually dependent:

1) from the right-click menu export the first namespace to the vertical header of the dependency matrix.

2) export the second namespace to the horizontal header of the dependency matrix.

3) double-click the black matrix cell (it is black because of mutual dependency).

4) in the matrix command bar, click the button: Remove empty Row(s) and Column(s).

At this point, the dependency matrix shows types involved into the coupling.

Some refactoring that helps uncouple two namespaces mutually dependent include:

• Moving one or several types from the low-level namespaces to the high-level one, or do the opposite.

• Use Inversion of Control (IoC): http://en.wikipedia.org/wiki/Inversion_of_control This can consist in creating new interfaces in the low-level namespace, implemented by classes in the high-level namespace. This way low-level code can consume high-level code through interfaces, without using directly high-level implementations. Interfaces can be passed to low-level code through the high-level namespace code, or through even higher-level code. In related documentations you can see these interfaces named as callbacks, and the overall pattern is also known as Dependency Injection (DI): http://en.wikipedia.org/wiki/Dependency_injection

Rule warning: Avoid namespaces dependency cycles

• Rule Description:

This rule lists all application namespace dependency cycles. Each row shows a different cycle, indexed with one of the namespace entangled in the cycle.

To browse a cycle on the dependency graph or the dependency matrix, right click a cycle cell and export the matched namespaces to the dependency graph or matrix.

In the matrix, dependency cycles are represented with red squares and black cells. To easily browse dependency cycles, the dependency matrix comes with an option: Display Direct and Indirect Dependencies

Read our white books relative to partitioning code, to know more about namespaces dependency cycles, and why avoiding them is a simple yet efficient solution to clean the architecture of a code base. http://www.ndepend.com/docs/white-books

• How to Fix Violations:

Removing first pairs of mutually dependent namespaces will eliminate most namespaces dependency cycles. This is why we suggest focusing on matches of the default rule Avoid namespaces mutually dependent before dealing with the present rule.

Once solving all mutually dependent namespaces, remaining cycles matched by the present rule necessarily involve 3 or more namespaces like in: A is using B is using C is using A. Such cycle can be broken by identifying which namespace should be at the lower-level. For example if B should be at the lower-level, then it means C should be at the higher-level and to break the cycle, you just have to remove the dependency from B to C, with a pattern described in the HowToFix section of the rule Avoid namespaces mutually dependent.

Rule warning: Namespaces with poor cohesion (RelationalCohesion)

• Rule Description:

This rule computes the Relational Cohesion metric for the application namespaces, and warns about wrong values.

The Relational Cohesion for a namespace, is the total number of relationship between types of the namespaces, divided by the number of types. In other words it is the average number of types in the namespace used by a type in the namespace.

As classes inside an namespace should be strongly related, the cohesion should be high. On the other hand, a value which is too high may indicate over-coupling. A good range for Relational Cohesion is 1.5 to 4.0.

Notice that namespaces with less than 20 types are ignored.

• How to Fix Violations:

Matches of this present rule might reveal either namespaces with specific coding constraints (like code generated that have particular structure) either issues in design.

In the second case, refactoring sessions can be planned to increase the overall design and code maintainability.

Critical Rule warning: Potentially dead Types

• Rule Description:

This rule lists potentially dead types. A dead type is a type that can be removed because it is never used by the program.

This rule lists not only types not used anywhere in code, but also types used only by types not used anywhere in code. This is why this rule comes with a column TypesusingMe and this is why there is a code metric named depth:

• A depth value of 0 means the type is not used.

• A depth value of 1 means the type is used only by types not used.

• etc…

By reading the source code of this rule, you'll see that by default, public types are not matched, because such type might not be used by the analyzed code, but still be used by client code, not analyzed by NDepend. This default behavior can be easily changed.

• How to Fix Violations:

Static analysis cannot provide an exact list of dead types, because there are several ways to use a type dynamically (like through reflection).

For each type matched by this query, first investigate if the type is used somehow (like through reflection). If the type is really never used, it is important to remove it to avoid maintaining useless code. If you estimate the code of the type might be used in the future, at least comment it, and provide an explanatory comment about the future intentions.

If a type is used somehow, but still is matched by this rule, you can tag it with the attribute IsNotDeadCodeAttribute found in NDepend.API.dll to avoid matching the type again. You can also provide your own attribute for this need, but then you'll need to adapt this code rule.

Critical Rule warning: Potentially dead Methods

• Rule Description:

This rule lists potentially dead methods. A dead method is a method that can be removed because it is never called by the program.

This rule lists not only methods not called anywhere in code, but also methods called only by methods not called anywhere in code. This is why this rule comes with a column MethodsCallingMe and this is why there is a code metric named depth:

• A depth value of 0 means the method is not called.

• A depth value of 1 means the method is called only by methods not called.

• etc…

By reading the source code of this rule, you'll see that by default, public methods are not matched, because such method might not be called by the analyzed code, but still be called by client code, not analyzed by NDepend. This default behavior can be easily changed.

• How to Fix Violations:

Static analysis cannot provide an exact list of dead methods, because there are several ways to invoke a method dynamically (like through reflection).

For each method matched by this query, first investigate if the method is invoked somehow (like through reflection). If the method is really never invoked, it is important to remove it to avoid maintaining useless code. If you estimate the code of the method might be used in the future, at least comment it, and provide an explanatory comment about the future intentions.

If a method is invoked somehow, but still is matched by this rule, you can tag it with the attribute IsNotDeadCodeAttribute found in NDepend.API.dll to avoid matching the method again. You can also provide your own attribute for this need, but then you'll need to adapt this code rule.

Rule warning: Methods that could have a lower visibility

• Rule Description:

This rule warns about methods that can be declared with a lower visibility without provoking any compilation error. For example private is a visibility lower than internal which is lower than public.

Narrowing visibility is a good practice because doing so promotes encapsulation. The scope from which methods can be called is then reduced to a minimum.

Notice that methods tagged with one of the attribute NDepend.Attributes.CannotDecreaseVisibilityAttribute or NDepend.Attributes.IsNotDeadCodeAttribute, found in NDepend.API.dll are not matched. If you don't want to link NDepend.API.dll but still wish to rely on this facility, you can declare these attributes in your code.

• How to Fix Violations:

Declare each matched method with the specified optimal visibility in the CouldBeDeclared rule result column.

By default, this rule matches public methods. If you are publishing an API many public methods matched should remain public. In such situation, you can opt for the coarse solution to this problem by adding in the rule source code && !m.IsPubliclyVisible or you can prefer the finer solution by tagging each concerned method with CannotDecreaseVisibilityAttribute.

Rule warning: Types that could have a lower visibility

• Rule Description:

This rule warns about types that can be declared with a lower visibility without provoking any compilation error. For example private is a visibility lower than internal which is lower than public.

Narrowing visibility is a good practice because doing so promotes encapsulation. The scope from which types can be consumed is then reduced to a minimum.

Notice that types tagged with one of the attribute NDepend.Attributes.CannotDecreaseVisibilityAttribute or NDepend.Attributes.IsNotDeadCodeAttribute, found in NDepend.API.dll are not matched. If you don't want to link NDepend.API.dll but still wish to rely on this facility, you can declare these attributes in your code.

• How to Fix Violations:

Declare each matched type with the specified optimal visibility in the CouldBeDeclared rule result column.

By default, this rule matches public types. If you are publishing an API many public types matched should remain public. In such situation, you can opt for the coarse solution to this problem by adding in the rule source code && !m.IsPubliclyVisible or you can prefer the finer solution by tagging each concerned type with CannotDecreaseVisibilityAttribute.

Rule warning: Types that could be declared as private, nested in a parent type

• Rule Description:

This rule matches types that can be potentially nested and declared private into another type.

The conditions for a type to be potentially nested into a parent type are:

• the parent type is the only type consuming it,

• the type and the parent type are declared in the same namespace.

Declaring a type as private into a parent type promotes encapsulation. The scope from which the type can be consumed is then reduced to a minimum.

• How to Fix Violations:

Nest each matched type into the specified parent type and declare it as private.

However nested private types are hardly testable. Hence this rule might not be applied to types consumed directly by tests.

Rule warning: Avoid publicly visible constant fields

• Rule Description:

This rule warns about constant fields that are visible outside their parent assembly. Such field, when used from outside its parent assembly, has its constant value hard-coded into the client assembly. Hence, when changing the field's value, it is mandatory to recompile all assemblies that consume the field, else the program will run with different constant values in-memory. Certainly in such situation bugs are lurking.

• How to Fix Violations:

Declare matched fields as static readonly instead of constant. This way, the field value is safely changeable without the need to recompile client assemblies.

Notice that enumeration value fields suffer from the same potential pitfall. But enumeration values cannot be declared as static readonly hence the rule comes with the condition && !f.IsEnumValue to avoid matching these. Unless you decide to banish public enumerations, just let the rule as is.

Rule warning: Fields should be declared as private

• Rule Description:

This rule matches non-private and mutable fields. Mutable means that the field value can be modified. Typically mutable fields are non-constant, non-readonly fields.

Fields should be considered as implementation details and as a consequence they should be declared as private.

If something goes wrong with a non-private field, the culprit can be anywhere, and so in order to track down the bug, you may have to look at quite a lot of code.

A private field, by contrast, can only be assigned from inside the same class, so if something goes wrong with that, there is usually only one source file to look at.

• How to Fix Violations:

Declare a matched mutable field as private, or declare it as readonly.

Critical Rule warning: Constructors of abstract classes should be declared as protected or private

• Rule Description:

Constructors of abstract classes can only be called from derived classes.

Because a public constructor is creating instances of its class, and it is forbidden to create instances of an abstract type, as a consequence an abstract class with a public constructor is wrong design.

• How to Fix Violations:

To fix a violation of this rule, either declare the constructor as protected, or do not declare the type as abstract.

Rule warning: Avoid public methods not publicly visible

• Rule Description:

This rule warns about methods declared as public whose parent type is not declared as public.

In such situation public means, can be accessed from anywhere my parent type is visible. Some developers think this is an elegant language construct, some others find it misleading.

This rule can be deactivated if you don't agree with it. Read the whole debate here: http://ericlippert.com/2014/09/15/internal-or-public/

• How to Fix Violations:

Declare the method as internal if it is used outside of its type, else declare it as private.

Rule warning: Event handler methods should be declared private

• Rule Description:

Think of a event handler like for example OnClickButton(). Typically such method must be declared as private and shouldn't be invoked in other context than event firing.

• How to Fix Violations:

If you have the need that event handler method should be called from another class, then find a code structure that more closely matches the concept of what you're trying to do. Certainly you don't want the other class to click a button; you want your other class to do something that clicking a button also do.

Rule warning: Fields should be marked as ReadOnly when possible

• Rule Description:

This rule warns about instance and static fields that can be declared as readonly.

This source code of this rule is based on the conditon IField.IsImmutable. http://www.ndepend.com/api/webframe.html?NDepend.API~NDepend.CodeModel.IField~IsImmutable.html

A field that matches the condition IsImmutable is a field that is assigned only by constructors of its class.

For an instance field, this means its value will remain constant through the lifetime of the object.

For a static field, this means its value will remain constant through the lifetime of the program.

• How to Fix Violations:

Declare the field with the C# readonly keyword (ReadOnly in VB.NET). This way the intention that the field value shouldn't change is made explicit.

Rule warning: Structures should be immutable

• Rule Description:

An object is immutable if its state doesn’t change once the object has been created. Consequently, a structure or a class is immutable if its instances fields are only assigned inline or from constructor(s).

But for structure it is a bit different. Structures are value types which means instances of structures are copied when they are passed around (like through a method argument).

So if you change a copy you are changing only that copy, not the original and not any other copies which might be around. Such situation is very different than what happen with instances of classes. Hence developers are not used to work with modified values and doing so introduces confusion and is error-prone.

• How to Fix Violations:

Make sure matched structures are immutable. This way, all automatic copies of an original instance, resulting from being passed by value will hold the same values and there will be no surprises.

If your structure is immutable then if you want to change a value, you have to consciously do it by creating a new instance of the structure with the modified data.

Rule warning: Property Getters should be immutable

• Rule Description:

It is not expected that a state gets modified when accessing a property getter. Hence doing so create confusion and property getters should be pure methods, they shouldn't assign any field.

• How to Fix Violations:

Make sure that matched property getters don't assign any field.

Notice the case of an object lazy-initialized when the property getter is accessed the first time. In such situation the getter assigns a field, but it is only once and from the client point of view, lazy initialization is an invisible implementation detail. If you are using a lot lazy initalization but still want to use the present rule, an option is to create a LazyInitializerAttribute that tags concerned property getters, and modify the present rule to avoid matching them.

Rule warning: Avoid static fields with a mutable field type

• Rule Description:

This rule warns about static fields that can be assigned (i.e they are not declared as readonly). This rule also warns about readonly static fields whose field type is mutable. In both cases, each matched static field is holding a state that can be modified.

In Object-Oriented-Programming the natural artifact to hold states that can be modified is instance fields. Hence such static fields create confusion at runtime.

More discussion on the topic can be found here: http://codebetter.com/patricksmacchia/2011/05/04/back-to-basics-usage-of-static-members/

• How to Fix Violations:

If the static field is just assigned once in the program lifetime, make sure to declare it as readonly and assign it inline, or from the static constructor.

Else, to fix violations of this rule, make sure to hold mutable states through objects that are passed explicitly everywhere they need to be consumed, in opposition to mutable object hold by a static field that makes it modifiable from a bit everywhere in the program.

Rule warning: A field must not be assigned from outside its parent hierarchy types

• Rule Description:

This rule is related to the rule Fields should be declared as private. It matches any public or internal, mutable field that is assigned from outside its parent class and subclasses.

Fields should be considered as implementation details and as a consequence they should be declared as private.

If something goes wrong with a non-private field, the culprit can be anywhere, and so in order to track down the bug, you may have to look at quite a lot of code.

A private field, by contrast, can only be assigned from inside the same class, so if something goes wrong with that, there is usually only one source file to look at.

• How to Fix Violations:

Matched fields must be declared as protected and even better as private. Alternatively, if the field can reference immutable states, it can remain visible from the outside, but then must be declared as readonly.

Critical Rule warning: Don't assign a field from many methods

• Rule Description:

A field assigned from many methods is a symptom of bug-prone code. Notice that:

• For an instance field, constructor(s) of its class that assign the field are not counted.

• For a static field, the class constructor that assigns the field is not counted.

The default threshold for instance fields is assigned by more than 4 methods. Such situation makes harder to anticipate the field state during runtime. The code is then complicated to read, hard to debug and hard to maintain. Hard-to-solve bugs due to corrupted state are often the consequence of fields anarchically assigned.

The situation is even more complex if the field is static. Indeed, such situation potentially involves global random accesses from various parts of the application. This is why this rule provides a lower threshold equals to assigned by more than 2 methods for static fields.

If the object containing such field is meant to be used from multiple threads, there are alarming chances that the code is unmaintainable and bugged. When multiple threads are involved, the rule of thumb is to use immutable objects.

If the field type is a reference type (interfaces, classes, strings, delegates) corrupted state might result in a NullReferenceException. If the field type is a value type (number, boolean, structure) corrupted state might result in wrong result not even signaled by an exception thrown.

• How to Fix Violations:

There is no straight advice to refactor the number of methods responsible for assigning a field. Solutions often involve rethinking and then rewriting a complex algorithm. Such field can sometime become just a variable accessed locally by a method or a closure. Sometime, just rethinking the life-time and the role of the parent object allows the field to become immutable (i.e assigned only by the constructor).

Rule warning: Do not declare read only mutable reference types

• Rule Description:

This rule is violated when a public or internal type contains a public or internal read-only field whose field type is a mutable reference type.

This situation provides the wrong impression that the value can't change, when actually it's only the field value that can't change, but the object state can still change.

• How to Fix Violations:

To fix a violation of this rule, replace the field type with an immutable type, or declare the field as private.

Rule warning: Abstract base class should be suffixed with 'Base'

• Rule Description:

This rule warns about abstract classes whose names are not suffixed with Base. It is a common practice in the .NET world to suffix base classes names with Base.

Notice that this rule doesn't match abstract classes that are in a middle of a hierarchy chain. Only base classes that derive directly from System.Object are matched.

• How to Fix Violations:

Suffix the names of matched base classes with Base.

Rule warning: Methods name should begin with an Upper character

• Rule Description:

This rule warns about methods whose names don't start with an Upper character. It is a common practice in the .NET world to use Pascal Casing Style to name methods.

Pascal Casing Style : The first letter in the identifier and the first letter of each subsequent concatenated word are capitalized. For example: ComputeSize

• How to Fix Violations:

Pascal Case the names of matched methods.

Critical Rule warning: Avoid having different types with same name

• Rule Description:

This rule warns about multiple types with same name, that are defined in different application or third-party namespaces or assemblies.

Such practice create confusion and also naming collision in source files that use different types with same name.

• How to Fix Violations:

To fix a violation of this rule, rename concerned types.

Rule warning: Avoid prefixing type name with parent namespace name

• Rule Description:

This rule warns about situations where the parent namespace name is used as the prefix of a contained type.

For example a type named "RuntimeEnvironment" declared in a namespace named "Foo.Runtime" should be named "Environment".

Such situation creates naming redundancy with no readability gain.

• How to Fix Violations:

To fix a violation of this rule, remove the prefix from the type name.

Rule warning: Methods prefixed with 'Try' should return a boolean

• Rule Description:

When a method has a name prefixed with Try, it is expected that it returns a boolean, that reflects the method execution status, success or failure.

Such method usually returns a result through an out parameter. For example: System.Int32.TryParse(int,out string):bool

• How to Fix Violations:

To fix a violation of this rule, Rename the method, or transform it into an operation that can fail.

Rule warning: Avoid referencing source file out of Visual Studio project directory

• Rule Description:

A source file located outside of the VS project directory can be added through: > Add > Existing Items… > Add As Link

Doing so can be used to share types definitions across several assemblies. This provokes type duplication at binary level. Hence maintainability is degraded and subtle versioning bug can appear.

This rule matches types whose source files are not declared under the directory that contains the related Visual Studio project file, or under any sub-directory of this directory.

This practice can be tolerated for certain types shared across executable assemblies. Such type can be responsible for startup related concerns, such as registering custom assembly resolving handlers or checking the .NET Framework version before loading any custom library.

• How to Fix Violations:

To fix a violation of this rule, prefer referencing from a VS project only source files defined in sub-directories of the VS project file location.

Rule warning: Namespace name should correspond to file location

• Rule Description:

For a solid code structure and organization, do mirror the namespaces hierarchy and the directories hierarchy containing source files.

Doing so is a widely accepted convention, and not respecting this convention will lead to less maintainable and less browsable source code.

This rule matches all types in such source file, whose location doesn't correspond to the type parent namespace. If a source file contains several such types (that are not necessarily in the same namespace) each type will result in a violation.

• How to Fix Violations:

To fix a violation of this rule, make sure that the type parent namespace and the directory sub-paths that contains the type source file, are mirrored.

Rule warning: Do not raise too general exception types

• Rule Description:

The following exception types are too general to provide sufficient information to the user:

• System.Exception

• System.ApplicationException

• System.SystemException

If you throw such a general exception type in a library or framework, it forces consumers to catch all exceptions, including unknown exceptions that they do not know how to handle.

This rule matches methods that create an instance of such general exception class.

• How to Fix Violations:

To fix a violation of this rule, change the type of the thrown exception to either a more derived type that already exists in the framework, or create your own type that derives from System.Exception.

Rule warning: Collection properties should be read only

• Rule Description:

A writable collection property allows a user to replace the collection with a completely different collection. A read-only property stops the collection from being replaced but still allows the individual members to be set. If replacing the collection is a goal, the preferred design pattern is to include a method to remove all the elements from the collection and a method to re-populate the collection. See the Clear() and AddRange() methods of the System.Collections.Generic.List<T> class for an example of this pattern.

Both binary and XML serialization support read-only properties that are collections. The System.Xml.Serialization.XmlSerializer class has specific requirements for types that implement ICollection and System.Collections.IEnumerable in order to be serializable.

This rule matches property setter methods that assign a collection object.

• How to Fix Violations:

To fix a violation of this rule, make the property read-only and, if the design requires it, add methods to clear and re-populate the collection.

Rule warning: Don't use .NET 1.x HashTable and ArrayList

• Rule Description:

This rule warns about application methods that use a non-generic collection class, including ArrayList, HashTable, Queue, Stack or SortedList.

• How to Fix Violations:

List<T> should be preferred over ArrayList. It is generic hence you get strongly typed elements. Also, it is faster with T as a value types since it avoids boxing.

For the same reasons:

• Dictionary<K,V> should be prevered over HashTable.

• Queue<T> should be prevered over Queue.

• Stack<T> should be prevered over Stack.

• SortedDictionary<K,V> or SortedList<K,V> should be prevered over SortedList.

You can be forced to use non generic collections because you are using third party code that requires working with these classes or because you are coding with .NET 1.x, but nowadays this situation should question about using newer updates of .NET. .NET 1.x is an immature platform conpared to newer .NET updates.

Rule warning: P/Invokes should be static and not be visible

• Rule Description:

Methods that are marked with the DllImportAttribute attribute (or methods that are defined by using the Declare keyword in Visual Basic) use Platform Invocation Services to access unmanaged code.

Such methods should not be exposed. By keeping these methods private or internal, you make sure that your library cannot be used to breach security by allowing callers access to unmanaged APIs that they could not call otherwise.

This rule matches methods tagged with DllImportAttribute attribute that are declared as public or declared as non-static.

• How to Fix Violations:

To fix a violation of this rule, change the access level of the method and/or declare it as static.

Rule warning: Move P/Invokes to NativeMethods class

• Rule Description:

Platform Invocation methods, such as those that are marked by using the System.Runtime.InteropServices.DllImportAttribute attribute, or methods that are defined by using the Declare keyword in Visual Basic, access unmanaged code. These methods should be in one of the following classes:

• NativeMethods - This class does not suppress stack walks for unmanaged code permission. (System.Security.SuppressUnmanagedCodeSecurityAttribute must not be applied to this class.) This class is for methods that can be used anywhere because a stack walk will be performed.

• SafeNativeMethods - This class suppresses stack walks for unmanaged code permission. (System.Security.SuppressUnmanagedCodeSecurityAttribute is applied to this class.) This class is for methods that are safe for anyone to call. Callers of these methods are not required to perform a full security review to make sure that the usage is secure because the methods are harmless for any caller.

• UnsafeNativeMethods - This class suppresses stack walks for unmanaged code permission. (System.Security.SuppressUnmanagedCodeSecurityAttribute is applied to this class.) This class is for methods that are potentially dangerous. Any caller of these methods must perform a full security review to make sure that the usage is secure because no stack walk will be performed.

These classes are declared as static internal. The methods in these classes are static and internal.

This rule matches P/Invoke methods not declared in such NativeMethods class.

• How to Fix Violations:

To fix a violation of this rule, move the method to the appropriate NativeMethods class. For most applications, moving P/Invokes to a new class that is named NativeMethods is enough.

Rule warning: Don't create threads explicitly

• Rule Description:

This code rule warns about methods that create threads explicitly by creating an instance of the class System.Threading.Thread.

Prefer using the thread pool instead of creating manually your own threads. Threads are costly objects. They take approximately 200,000 cycles to create and about 100,000 cycles to destroy. By default they reserve 1 Mega Bytes of virtual memory for its stack and use 2,000-8,000 cycles for each context switch.

As a consequence, it is preferable to let the thread pool recycle threads.

• How to Fix Violations:

Instead of creating explicitly threads, use the Task Parralel Library (TPL) that relies on the CLR thread pool.

Introduction to TPL: https://msdn.microsoft.com/en-us/library/dd460717(v=vs.110).aspx

Base class should not use derivatives

• Rule Description:

In Object-Oriented Programming, the open/closed principle states: software entities (components, classes, methods, etc.) should be open for extension, but closed for modification. http://en.wikipedia.org/wiki/Open/closed_principle

Hence a base class should be designed properly to make it easy to derive from, this is extension. But creating a new derived class, or modifying an existing one, shouldn't provoke any modification in the base class. And if a base class is using some derivative classes somehow, there are good chances that such modification will be needed.

Extending the base class is not anymore a simple operation, this is not good design.

• How to Fix Violations:

Understand the need for using derivatives, then imagine a new design, and then refactor.

Typically an algorithm in the base class needs to access something from derived classes. You can try to encapsulate this access behind an abstract or a virtual method.

If you see in the base class some conditions on typeof(DerivedClass) not only urgent refactoring is needed. Such condition can easily be replaced through an abstract or a virtual method.

Sometime you'll see a base class that creates instance of some derived classes. In such situation, certainly using the factory method pattern http://en.wikipedia.org/wiki/Factory_method_pattern or the abstract factory pattern http://en.wikipedia.org/wiki/Abstract_factory_pattern will improve the design.

Rule warning: Class shouldn't be too deep in inheritance tree

• Rule Description:

This rule warns about classes having 3 or more base classes. Notice that third-party base classes are not counted because this rule is about your code design, not third-party libraries consumed design.

In theory, there is nothing wrong having a long inheritance chain, if the modelization has been well thought out, if each base class is a well-designed refinement of the domain.

In practice, modeling properly a domain demands a lot of effort and experience and more often than not, a long inheritance chain is a sign of confused design, that will be hard to work with and maintain.

• How to Fix Violations:

In Object-Oriented Programming, a well-known motto is Favor Composition over Inheritance.

This is because inheritance comes with pitfalls. In general, the implementation of a derived class is very bound up with the base class implementation. Also a base class exposes implementation details to its derived classes, that's why it's often said that inheritance breaks encapsulation.

On the other hands, Composition favors binding with interfaces over binding with implementations. Hence, not only the encapsulation is preserved, but the design is clearer, because interfaces make it explicit and less coupled.

Hence, to break a long inheritance chain, Composition is often a powerful way to enhance the design of the refactored underlying logic.

Rule warning: Class with no descendant should be sealed if possible

• Rule Description:

If a non-static class isn't declared with the keyword sealed, it means that it can be subclassed everywhere the non-sealed class is visible.

Making a class a base class requires significant design effort. Subclassing a non-sealed class, not initially designed to be subclassed, will lead to unanticipated design issue.

Most classes are non-sealed because developers don't care about the keyword sealed, not because the primary intention was to write a class that can be subclassed.

There are minor performance gain in declaring a class as sealed. But the real benefit of doing so, is actually to express the intention: this class has not be designed to be a base class, hence it is not allowed to subclass it.

Notice that by default this rule matches also public class. If you are developing a framework with classes that are intended to be subclassed by your clients, just uncomment the line && !t.IsPublic.

• How to Fix Violations:

For each matched class, take the time to assess if it is really meant to be subclassed. Certainly most matched class will end up being declared as sealed.

Rule warning: Overrides of Method() should call base.Method()

• Rule Description:

Typically overrides of a base method, should refine or complete the behavior of the base method. If the base method is not called, the base behavior is not refined but it is replaced.

Violations of this rule are a sign of design flaw, especially if the actual design provides valid reasons that advocates that the base behavior must be replaced and not refined.

• How to Fix Violations:

You should investigate if inheritance is the right choice to bind the base class implementation with the derived classes implementations. Does presenting the method with polymorphic behavior through an interface, would be a better design choice?

In such situation, often using the design pattern template method http://en.wikipedia.org/wiki/Template_method_pattern might help improving the design.

Do not hide base class methods

• Rule Description:

Method hiding is when a base class has a non-virtual method M(), and a derived class has also a method M() with the same signature. In such situation, calling base.M() does something different than calling derived.M().

Notice that this is not polymorphic behavior. With polymorphic behavior, calling both base.M() and derived.M() on an instance object of derived, invoke the same implementation.

This situation should be avoided because it obviously leads to confusion. This rule warns about all method hiding cases in the code base.

• How to Fix Violations:

To fix a violation of this rule, remove or rename the method, or change the parameter signature so that the method does not hide the base method.

However method hiding is for those times when you need to have two things to have the same name but different behavior. This is a very rare situations, described here: http://blogs.msdn.com/b/ericlippert/archive/2008/05/21/method-hiding-apologia.aspx

Rule warning: A stateless class or structure might be turned into a static type

• Rule Description:

This rule matches classes and structures that are not static, nor generic, that doesn't have any instance fields, that doesn't implement any interface nor has a base class (different than System.Object).

Such class or structure is a stateless collection of pure functions, that doesn't act on any this object data. Such collection of pure functions is better hosted in a static class. Doing so simplifies the client code that doesn't have to create an object anymore to invoke the pure functions.

• How to Fix Violations:

Declare all methods as static and transform the class or structure into a static class.

Rule warning: Non-static classes should be instantiated or turned to static

• Rule Description:

If the constructors of a class are never called, the class is never instantiated, and should be defined as a static class.

However this rule doesn't match instantiation through reflection. As a consequence, plug-in root classes, instantiated through reflection via IoC frameworks, can be false positives for this rule.

Notice that by default this rule matches also public class. If you are developing a framework with classes that are intended to be instantiated by your clients, just uncomment the line !t.IsPublic.

• How to Fix Violations:

First it is important to investigate why the class is never instantiated. If the reason is the class hosts only static methods then the class can be safely declared as static.

Others reasons like, the class is meant to be instantiated via reflection, or is meant to be instantiated only by client code should lead to adapt this rule code to avoid these matches.

Rule warning: Methods should be declared static if possible

• Rule Description:

When an instance method can be safely declared as static you should declare it as static.

Whenever you write a method, you fulfill a contract in a given scope. The narrower the scope is, the smaller the chance is that you write a bug.

When a method is static, you can't access non-static members; hence, your scope is narrower. So, if you don't need and will never need (even in subclasses) instance fields to fulfill your contract, why give access to these fields to your method? Declaring the method static in this case will let the compiler check that you don't use members that you do not intend to use.

Declaring a method as static if possible is also good practice because clients can tell from the method signature that calling the method can't alter the object's state.

Doing so, is also a micro performance optimization, since a static method is a bit cheaper to invoke than an instance method, because the this reference* doesn't need anymore to be passed.

Notice that if a matched method is a handler, bound to an event through code generated by a designer, declaring it as static might break the designer generated code, if the generated code use the this invocation syntax, (like this.Method()).

• How to Fix Violations:

Declare matched methods as static.

Since such method doesn't use any instance fields and methods of its type and base-types, you should consider if it makes sense, to move such a method to a static utility class.

Rule warning: Constructor should not call a virtual method

• Rule Description:

This rule matches constructors of a non-sealed class that call one or several virtual methods.

When an object written in C# is constructed, what happens is that constructors run in order from the base class to the most derived class.

Also objects do not change type as they are constructed, but start out as the most derived type, with the method table being for the most derived type. This means that virtual method calls always run on the most derived type, even when calls are made from the constructor.

When you combine these two facts you are left with the problem that if you make a virtual method call in a constructor, and it is not the most derived type in its inheritance hierarchy, then it will be called on a class whose constructor has not been run, and therefore may not be in a suitable state to have that method called.

Hence this situation makes the class fragile to derive from.

• How to Fix Violations:

Violations reported can be solved by re-designing object initialisation or by declaring the parent class as sealed, if possible.

The singleton pattern consists in enforcing that a class has just a single instance: http://en.wikipedia.org/wiki/Singleton_pattern At first glance, this pattern looks appealing, it is simple to implement, it adresses a common situation, and as a consequence it is widely used.

However, we discourage you from using singleton classes because experience shows that singleton often results in less testable and less maintainable code. Singleton is by-design, not testable. Each unit test should use their own objects while singleton forces multiple unit-tests to use the same instance object.

Also the singleton static GetInstance() method allows magic access to that single object and its state from wherever developers want! This potentially attractive facility unfortunatly ends up into unorganized/messy code that will require effort to be refactored.

More details available in these discussions: http://codebetter.com/patricksmacchia/2011/05/04/back-to-basics-usage-of-static-members/ http://adamschepis.com/blog/2011/05/02/im-adam-and-im-a-recovering-singleton-addict/

• How to Fix Violations:

This rule matches the classic syntax of singletons, where one static field hold the single instance of the parent class. We underline that the problem is this particular syntax, that plays against testability. The problem is not the fact that a single instance of the class lives at runtime.

Hence to fix matches fo this rule, creates the single instance at the startup of the program, and pass it to all classes and methods that need to access it.

If multiple singletons are identified, they actually form together a program execution context. Such context can be unified in a unique singleton context. Doing so will make it easier to propagate the context across the various program units.

Don't assign static fields from instance methods

• Rule Description:

Assigning static fields from instance methods leads to poorly maintainable and non-thread-safe code.

More discussion on the topic can be found here: http://codebetter.com/patricksmacchia/2011/05/04/back-to-basics-usage-of-static-members/

• How to Fix Violations:

If the static field is just assigned once in the program lifetime, make sure to declare it as readonly and assign it inline, or from the static constructor.

In Object-Oriented-Programming the natural artifact to hold states that can be modified is instance fields.

Hence to fix violations of this rule, make sure to hold assignable states through instance fields, not through static fields.

Rule warning: Avoid empty interfaces

• Rule Description:

Interfaces define members that provide a behavior or usage contract. The functionality that is described by the interface can be adopted by any type, regardless of where the type appears in the inheritance hierarchy. A type implements an interface by providing implementations for the members of the interface. An empty interface does not define any members. Therefore, it does not define a contract that can be implemented.

If your design includes empty interfaces that types are expected to implement, you are probably using an interface as a marker or a way to identify a group of types. If this identification will occur at run time, the correct way to accomplish this is to use a custom attribute. Use the presence or absence of the attribute, or the properties of the attribute, to identify the target types. If the identification must occur at compile time, then it is acceptable to use an empty interface.

• How to Fix Violations:

Remove the interface or add members to it. If the empty interface is being used to label a set of types, replace the interface with a custom attribute.

Avoid types initialization cycles

• Rule Description:

The class constructor (also called static constructor, and named cctor in IL code) of a type, if any, is executed by the CLR at runtime, the first time the type is used. A cctor doesn't need to be explicitly declared in C# or VB.NET, to exist in compiled IL code. Having a static field inline initialization is enough to have the cctor implicitly declared in the parent class or structure.

If the cctor of a type t1 is using the type t2 and if the cctor of t2 is using t1, some type initialization unexpected and hard-to-diagnose buggy behavior can occur. Such a cyclic chain of initialization is not necessarily limited to two types and can embrace N types in the general case. More information on types initialization cycles can be found here: http://codeblog.jonskeet.uk/2012/04/07/type-initializer-circular-dependencies/

The present code rule enumerates types initialization cycles. Some false positives can appear if some lambda expressions are defined in cctors or in methods called by cctors. In such situation, this rule considers these lambda expressions as executed at type initialization time, while it is not necessarily the case.

• How to Fix Violations:

Types initialization cycles create confusion and unexpected behaviors. If several states hold by several classes must be initialized during the first access of any of those classes, a better design option is to create a dedicated class whose responsibility is to initialize and hold all these states.

• Rule Description:

This rule is executed only if a baseline for comparison is defined (diff mode).

This rule warns if a type publicly visible in the baseline, is not publicly visible anymore or if it has been removed. Clients code using such type will be broken.

• How to Fix Violations:

Make sure that public types that used to be presented to clients, still remain public now, and in the future.

If a public type must really be removed, you can tag it with System.ObsoleteAttribute with a workaround message during a few public releases, until it gets removed definitely. Notice that this rule doesn't match types removed that were tagged as obsolete.

Broken serializable types

• Rule Description:

This rule is executed only if a baseline for comparison is defined (diff mode).

This rule warns about breaking changes in types tagged with SerializableAttribute.

To do so, this rule searches for serializable type with serializable instance fields added or removed. Notice that it doesn't take account of fields tagged with NonSerializedAttribute.

From http://msdn.microsoft.com/library/system.serializableattribute.aspx : "All the public and private fields in a type that are marked by the SerializableAttribute are serialized by default, unless the type implements the ISerializable interface to override the serialization process. The default serialization process excludes fields that are marked with the NonSerializedAttribute attribute."

• How to Fix Violations:

Make sure that the serialization process of serializable types remains stable now, and in the future.

Else you'll have to deal with Version Tolerant Serialization that is explained here: https://msdn.microsoft.com/en-us/library/ms229752(v=vs.110).aspx

Avoid changing enumerations Flags status

• Rule Description:

This rule is executed only if a baseline for comparison is defined (diff mode).

This rule matches enumeration types that used to be tagged with FlagsAttribute in the baseline, and not anymore. It also matches the opposite, enumeration types that are now tagged with FlagsAttribute, and were not tagged in the baseline.

Being tagged with FlagsAttribute is a strong property for an enumeration. Not so much in terms of behavior (only the enum.ToString() method behavior changes when an enumeration is tagged with FlagsAttribute) but in terms of meaning: is the enumeration a range of values or a range of flags?

As a consequence, changing the FlagsAttributes status of an enumeration can have significant impact for its clients.

• How to Fix Violations:

Make sure the FlagsAttribute status of each enumeration remains stable now, and in the future.

C.R.A.P method code metric

• Rule Description:

This rule is executed only if some code coverage data is imported from some code coverage files.

Change Risk Analyzer and Predictor (i.e. CRAP) is a code metric that helps in pinpointing overly complex and untested code. Is has been first defined here: http://www.artima.com/weblogs/viewpost.jsp?thread=215899

The Formula is: CRAP(m) = CC(m)^2 * (1 – cov(m)/100)^3 + CC(m)

• where CC(m) is the cyclomatic complexity of the method m

• and cov(m) is the percentage coverage by tests of the method m

Matched methods cumulates two highly error prone code smells:

• A complex method, difficult to develop and maintain.

• Non 100% covered code, difficult to refactor without introducing any regression bug.

The highest the CRAP score, the more painful to maintain and error prone is the method.

An arbitrary threshold of 30 is fixed for this code rule as suggested by inventors.

Notice that no amount of testing will keep methods with a Cyclomatic Complexity highest than 30, out of CRAP territory.

Notice that this rule doesn't match too short method with less than 10 lines of code.

• How to Fix Violations:

In such situation, it is recommended to both refactor the complex method logic into several smaller and less complex methods (that might belong to some new types especially created), and also write unit-tests to full cover the refactored logic.

You'll find code impossible to cover by unit-tests, like calls to MessageBox.Show(). An infrastructure must be defined to be able to mock such code at test-time.

Complex methods partially covered by tests should be 100% covered

• Rule Description:

This rule is executed only if some code coverage data is imported from some code coverage files.

There are default rules that warn about complex methods to refactor. The present rule warns about complex methods that are already a bit covered by tests but not 100% covered by tests.

Such situation cumulates two highly error prone code smells:

• A complex method, difficult to develop and maintain.

• Non 100% covered code, difficult to refactor without creating any regression bug.

Because the complex method is already covered partially by tests, it might be not so costly to write more tests to full cover it.

• How to Fix Violations:

• Rule Description:

This rule is executed only if a baseline for comparison is defined (diff mode). This rule operates only on methods added or refactored since the baseline.

This rule is executed only if some code coverage data is imported from some code coverage files.

It is important to write code mostly covered by tests to achieve maintainable and non-error-prone code.

In real-world, many code bases are poorly covered by tests. However it is not practicable to stop the development for months to refactor and write tests to achieve high code coverage ratio.

Hence it is recommended that each time a method (or a type) gets refactored, the developer takes the time to write associated unit-tests to cover it.

Doing so will help to increase significantly the maintainability of the code base. You'll notice that quickly, refactoring will also be driven by testability, and as a consequence, the overall code structure and design will increase as well.

Types 95% to 99% covered

• Rule Description:

Often covering the few percents of remaining uncovered code of a class, requires as much work as covering the first 90%. For this reason, often teams estimate that 90% coverage is enough. However untestable code usually means poorly written code which usually leads to error prone code. So it might be worth refactoring and making sure to cover the few uncovered lines of code because most tricky bugs might come from this small portion of hard-to-test code.

Not all classes should be 100% covered by tests (like UI code can be hard to test) but you should make sure that most of the logic of your application is defined in some easy-to-test classes, 100% covered by tests.

• How to Fix Violations:

Write more unit-tests dedicated to cover code not covered yet. If you find some hard-to-test code, it is certainly a sign that this code is not well designed and hence, needs refactoring.

Indirectly called by a test means that a test method calls a method, that calls a method… From this recursion, a code metric named depthOfCalledByTests is inferred, The value 1 means directly called by test, the value 2 means called by a method that is called by a test…

Overrides of virtual and abstract methods, called through polymorphism, are not listed. Methods solely invoked through a delegate are not listed. Methods solely invoked through reflection are not listed.

We advise to not include test assemblies in code analyzed by NDepend. We estimate that it is acceptable and practical to lower the quality gate of test code, because the important measures for tests are:

• The coverage ratio,

• And the amount of logic results asserted: This includes both assertions in test code, and assertions in code covered by tests, like Code Contract assertions and Debug.Assert(…) assertions.

But if you wish to run this code query, you'll need to consider test assemblies in your list of application assemblies analyzed by NDepend.

Wrong usage of IsNotDeadCodeAttribute

Critical Rule warning: Potentially dead Types

• Rule Description:

This rule lists potentially dead types. A dead type is a type that can be removed because it is never used by the program.

This rule lists not only types not used anywhere in code, but also types used only by types not used anywhere in code. This is why this rule comes with a column TypesusingMe and this is why there is a code metric named depth:

• A depth value of 0 means the type is not used.

• A depth value of 1 means the type is used only by types not used.

• etc…

By reading the source code of this rule, you'll see that by default, public types are not matched, because such type might not be used by the analyzed code, but still be used by client code, not analyzed by NDepend. This default behavior can be easily changed.

• How to Fix Violations:

Static analysis cannot provide an exact list of dead types, because there are several ways to use a type dynamically (like through reflection).

For each type matched by this query, first investigate if the type is used somehow (like through reflection). If the type is really never used, it is important to remove it to avoid maintaining useless code. If you estimate the code of the type might be used in the future, at least comment it, and provide an explanatory comment about the future intentions.

If a type is used somehow, but still is matched by this rule, you can tag it with the attribute IsNotDeadCodeAttribute found in NDepend.API.dll to avoid matching the type again. You can also provide your own attribute for this need, but then you'll need to adapt this code rule.

Potentially dead Fields

• Rule Description:

This rule lists potentially dead fields. A dead field is a field that can be removed because it is never used by the program.

By reading the source code of this rule, you'll see that by default, public fields are not matched, because such field might not be used by the analyzed code, but still be used by client code, not analyzed by NDepend. This default behavior can be easily changed. Some others default rules in the Visibility group, warn about public fields.

More restrictions are applied by this rule because of some by-design limitations. NDepend mostly analyzes compiled IL code, and the information that an enumeration value or a literal constant (which are fields) is used is lost in IL code. Hence by default this rule won't match such field.

• How to Fix Violations:

Static analysis cannot provide an exact list of dead fields, because there are several ways to assign or read a field dynamically (like through reflection).

For each field matched by this query, first investigate if the field is used somehow (like through reflection). If the field is really never used, it is important to remove it to avoid maintaining a useless code element.

If a field is used somehow, but still is matched by this rule, you can tag it with the attribute IsNotDeadCodeAttribute found in NDepend.API.dll to avoid matching the field again. You can also provide your own attribute for this need, but then you'll need to adapt this code rule.

No fields matched

Wrong usage of IsNotDeadCodeAttribute

• Rule Description:

The attribute NDepend.Attributes.IsNotDeadCodeAttribute is defined in NDepend.API.dll. This attribute is used to mean that a code element is not used directly, but is used somehow, like through reflection.

This attribute is used in the dead code rules, Potentially dead Types, Potentially dead Methods and Potentially dead Fields. If you don't want to link NDepend.API.dll, you can use your own IsNotDeadCodeAttribute and adapt the source code of this rule, and the source code of the dead code rules.

In this context, this code rule matches code elements (types, methods, fields) that are tagged with this attribute, but still used directly somewhere in the code.

• How to Fix Violations:

Just remove IsNotDeadCodeAttribute tagging of types, methods and fields matched by this rule because this tag is not useful anymore.

No types matched
