[Microsoft] 'Build and Run' Deployment fails on HoloLens that is attached via USB

How to reproduce:
1. Create a new Unity project (or open the attached one)
2. In Build Settings
- Make sure the Target Platform is set to UWP
- Target Device - HoloLens
- Architecture - x86
- Visual Studio Version - Visual Studio 2017
- Build and Run on - USB Device
- Development Build, Script Debugging, Wait For Manager Debugger - all enabled
3. Attach a HoloLens device to the computer via USB
4. 'Build and Run' the project

Expected result: The project is successfully built and deployed on the attached HoloLens device.
Actual result: Build fails with deployment failure (see the error message below).

  1. Resolution Note (2019.3.X):

    After discussing further with Microsoft, we are not going to be able to fix this. They have been unable to provide us with an alternate API we can use here. It seems the previous API we are using is no longer supported on HoloLens.

    Hi,

    May I ask what is the solution then to deploy unity app to hololens ? Or is it just that Unity is not compatible with Hololens anymore ?
