## What it is
The official C# extension for Visual Studio Code, providing rich language support via a Language Server Protocol server powered by Roslyn and Razor. It ships alongside C# Dev Kit and offers IntelliSense, navigation, refactoring, formatting, and linting for C# projects.

## Use cases
- c# intellisense and autocomplete in vscode
- go to definition and find all references for c#
- refactor c# code in visual studio code
- format and lint c# files in vscode
- debug and edit .csproj solutions in vscode
- legacy .NET Framework projects with OmniSharp in vscode

## When to choose
- you write C# in Visual Studio Code and want official, actively maintained language support
- you want Roslyn-powered IntelliSense, navigation, and refactoring
- you use C# Dev Kit and need its required C# language extension

## When to avoid
- you use Visual Studio (full IDE) rather than VS Code
- you need a language server for a language other than C#
- you work on pre-.NET 6 projects and don't want to configure the legacy OmniSharp server path
