The record

Purpose: Roslynator is a set of code analysis tools for C#, powered by Roslyn.
IDE features: Its IDE extensions provide refactorings and fixes for compiler diagnostics.
Analyzers: Analyzers are not included in the IDE extensions and are provided through NuGet packages.
Editor support: The project lists extensions for Visual Studio 2026, Visual Studio 2022, VS Code, and Open VSX.
VS Code requirement: The VS Code extension requires legacy OmniSharp with dotnet.server.useOmnisharp set to true; it does not work with C# Dev Kit.
CLI: The command-line tool installs with dotnet tool install -g roslynator.dotnet.cli.
CI integration: The Roslynator CLI is integrated in MegaLinter, an open-source linter aggregator for CI.
Configuration: EditorConfig settings can configure analyzers, refactorings, and compiler diagnostic fixes.
Testing: The project provides a testing framework for unit testing analyzers, refactorings, and code fixes.
Client libraries: Its .NET client libraries extend the Roslyn API and do not include analyzers or refactorings.
Security support: The security policy supports version 5.x, CLI 0.x, and the Visual Studio 2026 and VS Code extensions; versions below 5.0 and Visual Studio 2022 extensions are out of support.
Vulnerability reporting: The project asks users to report suspected vulnerabilities through GitHub issues and says it will release a patch as soon as possible once confirmed.
License: The repository states that its files are licensed under Apache License 2.0.
Audience: The tools are for C# code analysis, refactoring, and compiler diagnostic fixes in Roslyn-based development environments.
