Hi Guys,
I got the error message after my upgrade:
Parser Error Message: Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
The following DLL's needed to be copied from the old (0.7.820) installation package:
"System.Web.Extensions.Design.dll"
"System.Web.Extensions.dll"
