Why won't HoloAcademy 250 build?
Today, Oct 17, 2107, came the 'Fall Creator Update'
So, I got latest Unity (2017.2.0f3) and the zip for the HA 250 'shared experience'
I had not yet updated everything (was using 2017.2b2).
Followed the tutorial to the point of the first time you can try running. It built out of Unity but has about 1000 errors in VS. So I go looking as to why.
I needed to install the 'Fall Creator Update' and reboot. Same problem.
I cleared all the created files (temp, library, uwp, all that). Same problem
In the 'Install these tools' section it says to get the 5.6 MRTP. This sounds fishy, obsolete. And, there's no link. Private forum. IS this still needed?
The many errors I get look like this:
Error CS0518 Predefined type 'System.String' is not defined or imported Assembly-CSharp, Assembly-CSharp-firstpass, Mixed Reality Academy Project Island C:\Users\me\AppData\Local\Temp.NETCore,Version=v5.0.AssemblyAttributes.cs 4 Active
So this is very broken. And the documentation (tutorial and 'install these') are all broken.
