What's new in 1.22.0
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.
Supported Operating Systems for Debugging
