Microsoft GDK PC Build & Run Functionality

Does anyone know where the PC build/run packaging feature moved to for the PC version of the Microsoft GDK v1.2.3 (package)? I have the GDK installed, and I can run samples. But where did the PC Build and Run option move to?

It used to look like this:

The Microsoft docs states that it is available in the menu, going to GDK → Build and Run. But my GDK option does not contain Build and Run.

Cheers,
Shaun

There is no longer a dedicated GDK UI for creating builds.

Check Player Settings → Microsoft GDK → Build for Microsoft GDK
Create a windows build via File → Build Settings.
