Product Features

NDepend is a .NET tool that provides deep insight into code bases. The tool empowers developers, architects and executives to make intelligent decisions on projects. The community name it the "Swiss Army Knife" for .NET programmers.

Easily Manage Large Projects

Most companies have large systems that work together, often in mysterious ways. NDepend's in-depth reporting and toolset can help your company enforce its own coding standards and maintain complex projects.

Code Rule and Code Query

Hundreds of default code rules to check against best practices. Support for Code Query over C# LINQ (CQLinq) to easily customize rules and query code.

Powerful Dependency Graph and Matrix

Explore how the code is actually structured and shed light on architectural flaws thanks to the most powerful code dependency graph and dependency matrix available in the tool industry.

Smart Technical Debt Estimation

For each issue, the cost to fix and the severity are estimated through smart and customizable C# formulas. Thus estimations proposed are realistic.

Continuous Code Quality

A unique approach to continuously keep the technical debt under control and reimburse it with time.

Quality Gates

Quality Gates are C# LINQ (CQLinq) queries that implement PASS/FAIL criteria to code quality.

In-Depth Issues Management

Explore the issues-set in a few clicks and focus your effort on what is urgent and important.

Harness Test Coverage Data

Import test coverage data, and make the most of it in the NDepend feature-rich context.

Monitor the Health of Your Application

NDepend allows your team to accurately gauge the overall health of your application, no matter how complex it is.

Trend Monitoring

Get Trend Charts about pretty much any code metrics to master the evolution of your application.

Code Diff since Baseline

Compare two versions of a code base and its issues set, and browse diff and changes in any way you can think of.

Warnings on Build Process Health

Be warned of potential build process problems before they end up causing friction and pain.

Reduce Friction Between Your Developer Teams

NDepend's reporting and analysis helps architects and developers to communicate and reduce confusion.

Continuous Integration Reporting

Integrate NDepend analysis into your build process and get highly customized and detailed reports to see progression and prevent code quality degradation.

Complexity and Diagrams

Spot too complex code at a glance thanks to unique diagramming capabilities.

Code Quality and Code Metrics

Lines of Code, Cyclomatic Complexity, Coupling, Nesting Depth, Rank, NDepend supports them all (and much more).

Working with Legacy Code is Now Easier

By mapping out the structure of the project, it is much easier to see how components and dependencies are connected.

Detect Dependency Cycles

Get rid of dependency cycles between components to achieve higher code maintainability.

Enforce Immutability and Purity

NDepend helps maintaining clean side-effects free code to write highly maintainable products.

Real-World Proof

Full Visual Studio and Azure DevOps integration, super fast and lightweight analysis, integration within all CI/DevOps systems, NDepend is conceived for real-world programmers.

NDepend.API and Power Tools

Write your own static analyzer based on NDepend.API, or tweak existing open-sources Power Tools.

Enforce Immutability and Purity

At runtime, program’s states are instance and static fields’ values. Controlling how/when/why states are changing is one of the most challenging programming task. This becomes incredibly difficult in multi-threaded environment. This is because potential side-effects due to a state change get too complicated to be understood.

Object-Oriented developers get more and more inspired by the functional programming approach where most states are immutable. An object is immutable if its state doesn’t change once it has been created. A method is pure if its execution doesn’t change any field state. Immutable objects and pure methods are two efficient ways to limit unexpected side-effects.

Through some dedicated CQLinq conditions and rules, NDepend lets assert immutability and purity on your classes and methods. The best place to start with this feature is to look at the list of default CQLinq rules and to read the associated documentation.
