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.

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.

The WinApp VS Code extension exists to make Windows app development feel at home in VS Code. It brings the Windows App Development CLI right into the editor, so you can initialize, run, debug, package, and sign Windows apps built with .NET, WPF, WinUI, C++, Electron, Rust, Tauri, or...

Often in applications, we write database queries. And often, the same query is executed again and again. To make queries against large tables faster, we can add an index. This is a general improvement for anyone accessing the table. However, there is a specially designed index called a...

If you use the Azure Cosmos DB vNext emulator, you probably know the local development loop: start the emulator, connect to it, create some resources, load test data, run queries, and inspect the results. Each step is straightforward, but together they add setup work before you can test...

The easy case is easy.

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...

It's fixed, but the fix isn't getting there.

Your agent skill calls an API. The moment you start evaluating it, every run either costs money or mutates production data. Learn how to mock APIs transparently so you can run evals without changing your skill or hitting real endpoints.
