Could not load type Microsoft.TeamFoundation.WorkItemTracking.Client.workItemTypeDeniedOrNotExistException

This is the exception we are getting when we try to view the workitems from the Team explorer in visual studio. The problem is, you installed the team explorer after you installed the Visual studio 2008 SP1. Because of this, all the workitem related dll’s are not referenced correctly. And result is below exception message.

Resolution:

To fix this issue, we just need to reinstall the visual studio sp1. So, the order should be

• Visual Studio
• Team Explorer
• Visual Studio SP1

Hope this helps to the people who are facing the same issue.
