TL;DR; Describes a Team Explorer error after installing Visual Studio 2008 SP1 RTM, troubleshooting steps taken, and issues with accessing version control features.

I received the following error box after installing VS2008 SP1 RTM:
Team Foundation Error
Could not load type ‘Microsoft.TeamFoundation.VersionControl.Controls.ItemsUpdatedExternallyEventArgs’ from assembly ‘Microsoft.TeamFoundation.VersionControl.Controls, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f57f11d50a3a
This stopped me accessing version control…a key part if you ask me.
The first thing I tried was to “Repair” Team Explorer, but that did not help, so I had a wee google…and found:
Problem of Team Explorer after installed Visual Studio 2008 SP1 beta which lead me to Re: Bug after installer the SP1 with work items and thus to the old favourite “reinstall the service pack!”
I have opened a thread ( Problems with Team Explorer after installed Visual Studio 2008 SP1 RTM ) on the MSDN forums…
If the reinstall of the SP fixes my problem, I will update there…
Update 2008-08-14: Nope, no fixie… I have sent my workstation to helpdesk for a rebuild. Humph!
Update 2008-08-15: I have installed SP1 sucessfully on 3 other computers…. Even ones that already had SP1 Beta1… Must just have been my workstation… double humph!
