The problem that I have is that after I have built my Unity project using Microsoft's Mixed Reality Toolkit and the Windows SDK 10.0.18362.0 I try to deploy it using the Hololens 2 emulator (version: 10.0.18362.1019). The result is that even though the emulator opens, my Unity application does not get deployed and the following error is being shown in Visual Studio's error list:
Please ensure that target device has developer mode enabled. Could not obtain a developer license on 192.168.9.57 due to error 80004005
I found several articles online that had the same problem like me, and they either referred to resetting the HoloLens device (which I do not need to do, since it is an emulator) or enabling the Developer Mode on the host machine (in my case a fully updated Windows 10 Enterprise Edition computer), which I already have. Nevertheless the error persists.
I just hope that there will be a way to get rid of this error and manage to deploy my Unity application onto the HoloLens emulator.
It seems that the solution is very simple. If you actually run Visual Studio as an Administrator the application is successfully deployed onto the emulator.
