Error when building Unity Build in Visual Studio
I'm trying to get into building stuff for the Hololense. Everything works fine in Unity (no Building Errors, can look around and all other stuff) but when I make a build (with and without Developer C# Checkbox) and try to buid it in Visual Studio (Emulator & Remote Desktop to the Hololense itself) I'll get around 10k-20k errors saying stuff like "Predefined type "System.Object" is not defined or imported" and "The type 'Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=188.8.131.52, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
Even when following the Microsoft Tutorials I get the same Errors.
I tried to clean and rebuild it, to build the whole thing new in Unity, change the .Net version and so on but even a completely new Project with nothing in the scene shows me 77 Errors.
I use VS 2017 and tried Unity 2017.01 and the Beta but same problems in both versions.
Sorry for my bad English ^^'
I really hope someone can help me
