Users may see the following message box when opening a solution in Team explorer after upgrading VS2010 Beta2 to RC.

Team Foundation Error
Could not load type 'Microsoft.TeamFoundation.Client.TeamFoundationServerBase' from assembly 'Microsoft.TeamFoundation.Client, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

OK

This can happen if you had the Beta2 Power Tools installed on your machine and then had uninstalled the Power Tools before uninstalling VS2010 Beta2. The uninstaller is not cleaning up all of the entries it should properly.
To resolve this please install the Beta2 Power Tools again, then uninstall the Beta2 Power Tools.
Note that an RC version of the power tools should be available soon. Bharry posted about it here.
