I am getting the same error as the original poster:
TypeLoadException: Could not load type 'Microsoft.AspNetCore.Mvc.ModelBinding.ValueProviderResultExtensions' from assembly 'Microsoft.AspNetCore.Mvc.Core, Version=184.108.40.206, Culture=neutral, PublicKeyToken=adb9793829ddae60'.
I have upgraded to the 2017.2.823 and this error is still there. Prior to the .823 version the grids were entirely broken, now all grids work but one where I have a particular client template. Other client templates work but this one particular one throws the above exception.
I'm trying to sort out what is different about this client template and I'll report back if I fond something.
