## What it is
StyleCop.Analyzers implements StyleCop style rules as Roslyn analyzers for C#, distributed as a NuGet package. It includes code fixes for many violations and supports configuration via stylecop.json and rule set files.

## Use cases
- enforce stylecop rules in c# projects
- check c# code style automatically in visual studio
- migrate from stylecop classic to roslyn analyzers
- auto-fix style violations with code fixes
- configure code style rule severity per project

## When to choose
- you want StyleCop rules enforced at build time in modern C# projects
- you need IDE-integrated diagnostics with quick-fix code fixes
- you want rule severity configurable via rulesets and stylecop.json

## When to avoid
- you need StyleCop settings via legacy Settings.StyleCop files
- you need analyzers for languages other than C#
- you want a standalone linter outside the .NET build/IDE toolchain

## Facets
- artifact type: library
- maturity: active
- function: linter, code-review, developer-tools
- domain: developer-tools, programming-languages, testing
- platform: dotnet, windows, cross-platform, editor-plugin
- tags: stylecop, roslyn-analyzers, code-style, static-analysis, csharp, nuget, code-fixes
