Remarks

On Desktop PCs, this tells an app when a Mixed Reality headset that is configured and ready is either attached to the PC or detached from the PC. Inspect the IsAvailable property to determine the current state of the system.

On HoloLens, this event will never occur, as holographic rendering is always available.
