Roslynator is a set of code analysis tools for C#, powered by Roslyn.
Analyzers are not included in Roslynator IDE extensions. Use Roslynator NuGet packages (e.g. Roslynator.Analyzers) for diagnostics.
Tools
- IDE extensions for:
- Visual Studio 2026 (refactorings and compiler diagnostic fixes; analyzers via NuGet)
- Visual Studio 2022 (last 4.x release; pin or use NuGet packages)
- VS Code (refactorings and compiler diagnostic fixes; analyzers via NuGet)
- Requires legacy OmniSharp (
dotnet.server.useOmnisharp:true). With C# Dev Kit, use NuGet packages instead.
- Requires legacy OmniSharp (
- Open VSX
- NuGet packages that contain a collection of analyzers
- Testing framework that allows unit testing of analyzers, refactorings, and code fixes
- .NET client libraries that extend the Roslyn API
- Command line tool
Documentation
Contributions
Contributions are welcome! See the developer documentation, contributing with agent skills, and open issues.
Agent skills in .claude/skills/ provide step-by-step workflows for Cursor and Claude Code (adding analyzers, refactorings, compiler fixes, and bug fixes). You can also read SKILL.md files directly as contributor guides. See CONTRIBUTING.md.
TIP: Bugfixes or small improvements can be implemented right away. Larger tasks, such as adding a new analyzer or refactoring, should be discussed first.
