Windows App SDK

Application development kit

Windows App SDK (codenamed Project Reunion) is a "framework package" from Microsoft that provides a unified application programming interface (API) and components that can be used to develop desktop apps for Windows 10 version 1809, Windows Server 2019, and their successors. Its purpose is to decouple capabilities that were previously tied to the UWP app model, allowing Win32 or .NET apps to take advantage of them as well.
