The ultimate static analysis suite for .NET developers to master code quality and architecture.

NDepend is a comprehensive static analysis tool specifically engineered for the .NET ecosystem, often referred to as the 'Swiss Army Knife' for .NET architects. It leverages a proprietary engine built on top of Roslyn to provide deep insights into code structure, dependencies, and quality metrics. In the 2026 market, NDepend maintains its dominance by offering CQLinq (Code Query over LINQ), allowing developers to treat their codebase as a database for custom rule creation and architectural enforcement. The tool excels in identifying 'spaghetti code' through interactive dependency graphs and matrices that remain performant even on multi-million line solutions. Its technical debt estimation model, based on the SQALE method, provides actionable financial metrics to stakeholders. Seamlessly integrating with Visual Studio 2022/2025 and modern DevSecOps pipelines like GitHub Actions and Azure DevOps, NDepend focuses on the 'Shift Left' philosophy, catching architectural erosion before it reaches production. By providing a baseline comparison between versions, it offers precise 'Diff' analysis, ensuring that quality gates are met during every pull request. Its 2026 positioning emphasizes high-performance local analysis coupled with rich, shareable HTML reports for distributed teams.

A specialized query language that allows querying code like data using LINQ syntax (e.g., from m in Methods where m.CyclomaticComplexity > 10 select m).
A compact visual representation of dependencies between thousands of components using a triangular matrix.
Compares two versions of a codebase to identify exactly which new issues or technical debt were introduced in a specific timeframe.
Uses standard SQALE formulas to estimate the 'Man-Days' required to fix specific code violations.
Overlays code change frequency (churn) with complexity to identify the most 'dangerous' areas of the code.
User-defined conditions that must be met (e.g., 'no new issues with severity > major') for a build to pass.
Visualizes the evolution of over 50 metrics (LoC, Debt, Coverage) over years of development.
Download the NDepend zip and extract to a local directory or install via Visual Studio Marketplace.
Launch the NDepend Visual Studio extension and attach it to an existing .NET solution.
Run the initial 'Power Tools' analysis to generate the first code metrics report.
Set the 'Baseline' to the current production version to track future regressions.
Explore the Dependency Graph to identify circular dependencies between namespaces.
Review the 'Technical Debt' dashboard to identify high-priority 'Debt' areas.
Customize CQLinq rules to match your organization's specific coding standards.
Integrate the NDepend.Console.exe into your CI/CD pipeline (e.g., Jenkins or GitHub Actions).
Configure 'Quality Gates' to automatically fail builds that introduce new critical issues.
Schedule automated HTML report generation for team-wide visibility.
