Faster C++ iterative builds with GitHub Copilot
Slow builds are a consistent theme of feedback from C++ developers. We built GitHub Copilot build performance for Windows so you can leverage Copilot to optimize your project’s build times. This workflow will find optimizations that bring your build times down. At first, we only measured the impact of build optimizations on full clean builds. While that number is valuable, we know that you are not rebuilding from scratch on most days. You edit a file and build, then repeat the process as part of your iterative loop. Working with customers after the public preview, we noticed that every now and then, the age...

Rethinking C++ Performance: Faster Code Navigation and GitHub Copilot Tools with Whole Codebase Indexing
In large C++ codebases, your code understanding and navigation depend on quickly determining how symbols, declarations, definitions, and references are connected across your project. In Visual Studio Insiders 18.9, the new whole codebase indexing (WCI) enhances the existing browse database via a deeper, more comprehensive indexing approach. This preview feature allows Visual Studio to access richer symbol information more efficiently in your C++ project, with faster lookups for core IntelliSense scenarios like Find All References and semantic file colorization. It also enables new experiences like CodeLens ref...
