Free (as in freedom) fork of the official vscode C# extension

free-omnisharp-vscode

This extension is published at open-vsx.org.

Announcements

The C# extension no longer ships with an included Mono & MSBuild Tools

.NET Framework builds of OmniSharp no longer ship with Mono or the MSBuild tooling (See announcement omnisharp-roslyn#2339). To ensure that the C# extension remains usable out of the box for .NET SDK projects, we have changed the default value of omnisharp.useModernNet to true.

If you still need Unity or .NET Framework support, you can set omnisharp.useModernNet to false in your VS Code settings and restart OmniSharp. Please see the Requirements section above to ensure necessary tooling is installed.

See issue #5120 for more details.

Emmet support in Razor files

To enable emmet support, add the following to your settings.json:

"emmet.includeLanguages": {
    "aspnetcorerazor": "html"
}

Semantic Highlighting

The C# semantic highlighting support is in preview. To enable, set editor.semanticHighlighting.enabled and csharp.semanticHighlighting.enabled to true in your settings. Semantic highlighting is only provided for code files that are part of the active project.

To really see the difference, try the new Visual Studio 2019 Light and Dark themes with semantic colors that closely match Visual Studio 2019.
