C++ Dependencies Without the Headache: vcpkg + Copilot CLI
At Pure Virtual C++ 2026, we build a C++ console app from an empty folder using CMake, MSVC, and GitHub Copilot CLI. This walkthrough shows a practical prompt sequence for dependency selection, reproducible builds, and controlled updates.
Pure Virtual C++ 2026 Is Tomorrow and On-Demand Sessions Are Now Available
The on-demand sessions for Pure Virtual C++ 2026 are available now on YouTube. Watch seven talks on SPGO, vcpkg + Copilot CLI, CMake Tools, PackageReference, MSVC upgrades, and C++23/26 status — then join us live tomorrow.
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...
Pure Virtual C++ 2026 [Meet the Speakers, Part 2]: The AI-Native C++ Developer Workflow
Pure Virtual C++ 2026 streams Tuesday, July 21, 2026 at 9:00 AM PT, a free, one-day virtual conference for the whole C++ community, live on YouTube (Microsoft Reactor) and Twitch, with on-demand recordings on the Visual Studio YouTube channel afterward. Register now → Welcome to part two of our Meet the Speakers series. In part one we looked at building and running faster. Today we turn to the theme shaping the future of development: the AI-native C++ developer workflow. Why this theme matters C++ development is evolving into an AI-native, agent-driven experience and it's happening everywhere you work, f...
Pure Virtual C++ 2026 [Meet the Speakers, Part 1]: Build Faster, Run Faster
Meet the speakers behind Pure Virtual C++ 2026. In part one, Ryan Shepherd and David Li show how to build faster and smaller with C++20 modules and GitHub Copilot build performance.
