This one had me baffled for a while.Thanks to Mr.Allan Thræn for getting this problem solved. It is actually a problem in the EPiServer CMS5 R2 SP1 And Visual Studio Integration, where an internal test dll (EPiServer.Blog_Accessor.dll) by accident has been included. That dll requires VS Team Test and if you don't have that installed you'll see the error above.

Solution:- The solution is easy, just delete the EPiServer.Blog_Accessor from your bin folder / remove it from your project.
