I was getting when entering play mode after upgrading to b8 and Burst preview 35:
Unexpected exception System.IO.FileNotFoundException: Could not load file or assembly ‘Smash, Version=0.3.0.0, Culture=neutral, PublicKeyToken=null’ or one of its dependencies.

First I thought it was the Burst compiler, but I the error remained after downgrading to preview 34, so I removed the incremental compiler and the error went away.
