What NDepend is

NDepend is a .NET code quality and security analysis tool for developers, architects, and executives. It provides hundreds of default static-analysis rules, plus custom rules and C# LINQ code queries through CQLinq. Interactive dependency graphs and matrices help explore code structure and architectural issues. Teams can define PASS, WARN, and FAIL quality or security criteria that can fail a build pipeline. NDepend integrates analysis into CI/CD pipelines and creates interactive web reports for tracking progression and preventing quality degradation. Reports and the interface can import issues from Roslyn Analyzers and ReSharper Code Inspections. Code metrics, trend charts, and imported test-coverage data support additional review. Listed integrations include Visual Studio, Azure DevOps/TFS, GitHub Actions, Jenkins, TeamCity, AppVeyor, Bamboo, and SonarQube. Analysis runs on premises, with code staying within the customer's infrastructure. Editions serve interactive developer use or build and continuous-integration servers.
