These experiences are available now as a Private Preview in Visual Studio 2026. Install Visual Studio 2026 and join the waitlist for Private Preview today.

C++ code editing tools for GitHub Copilot

C++ code editing tools for GitHub Copilot bring the precision of C++ IntelliSense to Visual Studio agent mode to enable faster and more accurate codebase-wide edits. This includes:

• Viewing all references across your codebase
• Understanding relevant metadata (e.g., type, declaration, and scope)
• Visualizing class inheritance hierarchies
• Tracing function call chains

See Perform wide-sweeping refactors using C++ code editing tools for GitHub Copilot on the C++ Team Blog for more information.

GitHub Copilot build performance for Windows

GitHub Copilot build performance for Windows uses the power of Build Insights to analyze your C++ build and suggest changes to improve performance. Check out Optimize Your C++ Build Times with GitHub Copilot on the C++ Team Blog to learn more.
