Mixedrealitytoolkit-unity: Using Unity 2017.2.0b2 with HoloToolkit causes Unity to not build project

[jessemcculloch]

Once I add the HTK to my project, even if I am not using anything in it, and I try to build for the HoloLens from Unity, it fails with the following errors, however, if I pull the HTK out of my assets folder, it builds just fine. I just tried this with the very latest merged code as of noon on 7/13 and am still seeing the same behavior.

Confirming that I also have this issue with 2017.2.0b2 and latest HTK

[jessemcculloch]

This appears to be a bug in Unity. If the option _Unity C# Projects_ is selected then the build fails with the above errors, however leaving this unchecked allows the build to complete successfully. Closing this issue and opening bug with Unity.

@jessemcculloch Link to the Unity bug ticket?

Possibly this one?

Claims fixed in 2017.3, but I haven't been hitting it in the 2017.2 MRTP builds (I haven't tried regular 2017.2 builds).

Thanks! We hit something with a similar error but turns out it was something else unrelated to the toolkit.

This was a known issue in Unity 2017.2.0b2 when C# Projects was checked during the UWP build (and is unrelated to the Toolkit itself). Should be fixed on non-beta releases. Are you seeing it elsewhere?
