Welcome to the C# extension for Visual Studio Code! This extension provides the following features inside VS Code:
- Lightweight development tools for .NET Core.
- Great C# editing support, including Syntax Highlighting, IntelliSense, Go to Definition, Find All References, etc.
- Debugging support for .NET Core (CoreCLR). NOTE: Mono debugging is not supported. Desktop CLR debugging has limited support.
- Support for project.json and csproj projects on Windows, macOS and Linux.
The C# extension is powered by OmniSharp.
The .NET 3.1.40x SDKs require version 16.7 of MSBuild.
For MacOS and Linux users who have Mono installed, this means you will need to set omnisharp.useGlobalMono to never until a version of Mono ships with MSBuild 16.7.
The .NET 5 SDK requires version 16.8 of MSBuild.
For Windows users who have Visual Studio installed, this means you will need to be on the latest Visual Studio 16.8 Preview.
For MacOS and Linux users who have Mono installed, this means you will need to set omnisharp.useGlobalMono to never until a version of Mono ships with MSBuild 16.8.

To enable emmet support, add the following to your settings.json:
"emmet.includeLanguages": {
"aspnetcorerazor": "html"
}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.
