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.

Bug fixes and support ends immediately for listed extensions, which will be marked as deprecated. Also, the deprecation specifically means that starred completions in the code completion lists, i.e. IntelliSense, will no longer be shown. Additionally, inline gray text suggestions will be removed and no new features will be added for listed extensions.
