Language and platform support
Visual Studio Live Share's features are intended to work across a diverse landscape of languages and application platforms. However, given the sheer number of variations, some platforms and languages are more complete than others. This document covers the current known state of a number of popular languages and platforms for currently supported features.
Visual Studio Code
All languages / platforms have same file intellisense (when the respective extension is installed), as well as colorization and co-editing support. The lists below covers advanced features currently without complete, universal support:

3 JavaScript / TypeScript debugging for Node or browser.
4 The respective extension for VS Code doesn't currently support debugging. As soon as it does, we will investigate adding co-debugging support to it.

9 Live Share doesn't currently support sharing windows/screens. Vote (👍) here.
Visual Studio
While most languages have some single file Intellisense support, there are some caveats outlined below. All languages/platforms support co-editing. The remainder of the list covers advanced features currently without complete, universal support:
Languages
| Language | Single-file language services | Project-wide language services | Co-Debugging |
|---|---|---|---|
| C# | ✅ | ✅ | ✅ |
| CSHTML | ✅ 1 | ✅ | |
| ASPX | ✅ 1 | ✅ | |
| HTML | ✅ | N/A | 2 |
| CSS | ✅ | N/A | N/A |
| JavaScript / TypeScript | ✅ | ✅ | ✅ 3 |
| C++ | ✅ | ✅ | ✅ |
| Python | ✅ | ✅ | |
| Markdown | ✅ | N/A | N/A |
| PowerShell | ✅ | N/A | ✅ |
| VB.NET | ✅ | ✅ | |
| VBHTML | ✅ 1 | ✅ | |
| XAML | ✅ | N/A | 4 |
| SQL / T-SQL | ✅ | N/A | |
| F# | ✅ | ✅ | |
| R | ❌ 5 | N/A | ✅ |
1 Gap: CSHTML, VBHTML, and ASPX have a known issues around embedded C#/VB support given code-behind C#/VB files are not resolved due to full intellisense not being implemented. Vote (👍) here on CSHTML/VBHTML. Vote (👍) here on ASPX.
2 Embedded JavaScript in HTML is supported when doing client debugging.
3 JavaScript / TypeScript debugging for Node or browser.
4 Though debugging XAML itself is technically N/A, debugging code-behind is supported.
5 Gap: R language service errors on the guest side on join and after every newline. Not supported. Vote (👍) here.
