Long build times are one of the top pain points for C++ projects. If you\u2019ve ever waited too long for a C++ build to finish, you know how much it can slow down your productivity. In past years, we introduced C++ Build Insights<\/a> to help you analyze traces and find bottlenecks. However, we know that embarking on these investigations manually can still take time and effort.<\/p>\n

To make this experience easier for C++ developers, we\u2019re excited to announce that GitHub Copilot build performance for Windows<\/strong> is now available in Private Preview<\/a> with the latest version of Visual Studio 2026 Insiders.<\/p>\n

New GitHub Copilot Capabilities<\/h2>\n

When you use this new capability in Visual Studio, GitHub Copilot will use an agent to:<\/p>\n

    \n
  1. Kick off a build and capture a trace for you<\/li>\n
  2. Identify expensive headers and other bottlenecks<\/li>\n
  3. Suggest and apply optimizations like precompiled headers<\/li>\n
  4. Validate changes through rebuilds so your code stays correct<\/li>\n
  5. Show you measurable improvements and recommend next steps<\/li>\n<\/ol>\n

    Instead of spending time manually optimizing your build, you can let the new GitHub Copilot build performance capability handle the heavy lifting while you focus on writing code.<\/p>\n
