The GDK Unity Package (PC Only) provided by Microsoft via GitHub has been deprecated as of December 31st, 2024. Alongside the release of April 2025 GDK, the Microsoft GDK documentation and GitHub now point to the new Microsoft GDK packages for Unity that provide capabilities to build GDK games across PC & Consoles.
If you are using Unity as your game engine and want to learn more about the supported GDK packages to use, please see these links:
