Unity Apps only in 2D on Hololens

Hey Developers!
I'm trying to get the Mixed Reality 250 to get working on my HoloLens but i have several problems:

1. I can't use Unity 5.6 or Unity2017.1 (I get 58 errors by just opening the project) so i have to use Unity2017.2
2. When launching the project on the hololens the app opens but just as a 2D window and not as a 3D application like it should be.
3. Even when just having a blank project and changing the mainCamera values manually it still appears only in 2D after deploying .

Has anyone experienced the same problem and knows how to debug it?
