Could not load type Microsoft.VisualStudio.Services.Common.VssHttpClientBase

If your getting the following error on your TFS server web interface odds are that you are using incompatible version between TFS and VS or other Microsoft product. The object in question was moved from the common Dll to another. In my case I installed TFS RC and then never version of VS2013, after that I got the error.

Could not load type ‘Microsoft.VisualStudio.Services.Common.VssHttpClientBase’ from assembly ‘Microsoft.VisualStudio.Services.Common, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’.

To remedy the situation I upgraded TFS 2013 with the RTM version. After the upgrade I’m not getting the error anymore ant the TFS web interface works as expected.
