Microsoft has begun the process of phasing out IntelliCode, its AI-assisted code completion tooling for Visual Studio Code, signaling a shift in how the company wants developers to access intelligent coding help. The move affects several IntelliCode-related extensions and marks the end of Microsoft’s standalone AI completion experience in VS Code.
In a notice posted on GitHub, Microsoft confirmed that multiple extensions are now deprecated, including IntelliCode, IntelliCode Completions, IntelliCode for C# Dev Kit, and IntelliCode API Usage Examples. Developers are being advised to uninstall the IntelliCode for C# Dev Kit and rely instead on built-in language server features powered by the Roslyn .NET compiler platform, or to adopt GitHub Copilot Chat for more advanced AI-driven assistance.
Despite the deprecation, core editing capabilities in Visual Studio Code will remain intact. Standard IntelliSense features such as code completion lists, signature help, hover details, and syntax highlighting will continue to be provided through Roslyn’s language server integration. However, IntelliCode-specific enhancements, such as starred recommendations in completion lists and inline gray text suggestions, will no longer be available.
Microsoft has also confirmed that support and bug fixes for the deprecated extensions have ended immediately, and no new features will be added. By directing developers toward GitHub Copilot Chat, the company is consolidating its AI coding strategy around a single, more capable assistant, reflecting a broader industry trend toward conversational and context-aware development tools.
