Roslynator is a set of code analysis tools for C#, powered by Roslyn.

IMPORTANT: Analyzers will be removed from Roslynator IDE extensions in the next major release. It's recommended to use Roslynator NuGet packages (e.g. Roslynator.Analyzers) instead.

• IDE extensions for:
  • Visual Studio
  • VS Code
    • Prerequisite is to use OmniSharp. Otherwise (i.e. C# Dev Kit), use NuGet packages with analyzers, refactorings and code fixes.
  • Open VSX
• NuGet packages that contain collection of analyzers
  • Roslynator.Analyzers
  • Roslynator.CodeAnalysis.Analyzers
  • Roslynator.Formatting.Analyzers
• Testing framework that allows unit testing of analyzers, refactoring and code fixes
• .NET client libraries that extend Roslyn API
• Command line tool

• Configuration
• Guides
• Roslynator CLI
• Roslynator Testing Framework
• Roslynator Client Libraries

Contributions are welcome! If you are interested please see:

• documentation for developers
• available issues

TIP: Bugfixes or small improvements can be implemented right away. Larger task like adding new analyzer or refactoring should be discussed first.
