The tool proposes a large number of features, from CI/CD Web Reporting to Quality Gate and Dependencies Visualization. For that reason, the community refers to it as the "Swiss Army Knife" for .NET Developers.

The main features of NDepend are:

Code rules through LINQ queries (CQLinq)

Live code queries and code rules through LINQ queries is the backbone of NDepend, all features use it extensively. Here are some sample code queries:

  • Base class should not use derivatives:

::code[lang=csharp] // Base class should not use derivatives warnif count > 0 from baseClass in JustMyCodeTypes where baseClass.IsClass && baseClass.NbChildren > 0 // <-- for optimization! let derivedClassesUsed = baseClass.DerivedTypes.UsedBy(baseClass) where derivedClassesUsed.Count() > 0 select new { baseClass, derivedClassesUsed } ::

::code[lang=csharp] // Avoid making complex methods even more complex (source code cyclomatic complexity) warnif count > 0 from m in JustMyCodeMethods where !m.IsAbstract && m.IsPresentInBothBuilds() && m.CodeWasChanged() let oldCC = m.OlderVersion().CyclomaticComplexity where oldCC > 6 && m.CyclomaticComplexity > oldCC select new { m, oldCC, newCC = m.CyclomaticComplexity, oldLoc = m.OlderVersion().NbLinesOfCode, newLoc = m.NbLinesOfCode, } ::

Additionally, the tool provides a live CQLinq query editor with code completion and embedded documentation.
