C# is the feature-rich, language support for C# and is shipped as part of C# Dev Kit. This version of the extension is currently in pre-release and available for you to use today.
C# is an extension that contributes to the C# Dev Kit extension for Visual Studio Code to provide performant and reliable language support. Under the hood, this extension is powered by a Language Server Protocol (LSP) Tools Host which integrates with open source components like Roslyn and Razor to provide rich type information and a faster, more reliable C# experience.
While it is possible to use the C# extension as a standalone extension, we highly recommend using C# Dev Kit.
- Installing C# Dev Kit will automatically install this extension as a required dependency
- Open a folder/workspace that contains a C# project (.csproj) and a C# solution (.sln) and the extension will activate.
Note: If working on a solution that requires versions prior to .NET 6, install a Full Framework runtime and MSBuild tooling.
- Set omnisharp.useModernNet to false and if you are on the pre-release verion, set dotnet.server.useOmnisharp to true
- Windows: .NET Framework along with MSBuild Tools
- MacOS/Linux: Mono with MSBuild
- Refactoring
- Code Navigation (GTD, FAR)
- Code Completions
- Roslyn powered semantic awareness
If you don’t want to take advantage of the great Language Server features, you can revert back to using OmniSharp in the pre-release extension by going to the Extension settings and setting dotnet.server.useOmnisharp to true. This will require that you restart VS Code to take effect. You can also switch back to the Switch to Release Version to revert back to the C# extension powered by OmniSharp.
To file a new issue to include all the related config information directly from vscode by entering the command pallette with Ctrl+Shift+P (Cmd+Shift+P on macOS) and running CSharp: Report an issue command. This will open a browser window with all the necessary information related to the installed extensions, dotnet version, mono version, etc. Enter all the remaining information and hit submit.
