Project Reunion Unveiled

At Microsoft Build 2020, Microsoft unveiled Project Reunion, which is envisioned for unifying and evolving the Windows developer platform to make it easier to build great apps that work across all the Windows 10 versions and devices people use.

For the past couple of years, Microsoft has been trying to break down the barrier between Win32 (also called the Windows API) and Universal Windows Platform (UWP) APIs.
 
Project Reunion expands this effort to make it easier to build a great Windows app. It will unify access to existing Win32 and UWP APIs and make them available decoupled from the OS, via tools like NuGet. This will provide a common platform for new apps.
 
Plus, it will help you update and modernize your existing apps with the latest functionality, whether they’re C++, .NET (including WPF, Windows Forms, and UWP) or React Native. As we decouple existing APIs and add new APIs, we are also doing the work to polyfill, as needed, so the APIs work down-level across supported versions of Windows.
