Microsoft is officially deprecating the IntelliCode AI-assisted code completion extensions for the Visual Studio Code editor, and is recommending that C# developers use the GitHub Copilot Chat conversational AI assistant instead.
A Microsoft post on GitHub lists the following VS Code extensions as being deprecated: IntelliCode, IntelliCode Completions, IntelliCode for C# Dev Kit, and IntelliCode API Usage Examples. The company recommends that developers uninstall the IntelliCode for C# Dev Kit extension and continue using the built-in language server support from Roslyn or install GitHub Copilot Chat for advanced suggestions and inline completions. In the wake of the deprecations, developers will get the same language server-powered completion lists (IntelliSense) along with other language server features such as signature help, hover information, and syntax highlighting from the Roslyn .NET compiler platform in VS Code.
