"The "AllowedRelatedFileExtensions" parameter is not supported by the "ResolveAssemblyReference" task. Verify the parameter exists on the task, and it is a settable public instance property."
Kind of a crap error in my opinion!
Uninstall and reinstall the .NET Framework 2.0 ( and every other .NET Framework for surety.)
If you get something like this message when going through "Install/Remove Programs" (start->control panel):
"Patch Package could not be opened"
during uninstall (like I did :((( ) then use this guy (I call him the "Software Eradicator" because he is ruthless so be careful):
Download the Windows Installer CleanUp Utility package now.
Download details: .NET Framework Version 2.0 Redistributable ...
And I installed the service pack too:
Download details: .NET Compact Framework 2.0 SP1 Redistributable
You are back on the road again.
