Team foundation error Could not load file or assembly Microsoft.Practices.EnterpriseLibrary.Common

Question

I am trying to edit the build definition of one of my builds on Visual Studio (specifically, changing the password). As soon as I am finished and press Ctrl+S I get the following error:

Team Foundation Error

Could not load file or assembly 'Microsoft.Practices.EnterpriseLibrary.Common, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf2856ad364e35' or one of its dependencies. The system cannot find the file specified.

I have looked into my build, dev and production servers and I can see the file and it is the correct version (5.0.414.0). Any idea what is going wrong here?

Answer 1

This was an issue entirely with Visual Studio on my local machine, not TFS.

Apparently when you edit a build definition, Team Explorer 2010 assumes you're doing it for your currently open solution. I still do not know why it could not find the assembly when it was clearly in my bin\Debug directory, but there you go.

The solution was a simple closing and re-opening Visual Studio. I was then able to edit and save the definition with the new parameter and promote to production appropriately.

Answer 2

Check if the assembly is included in your project and if it exist in the folder of your solution.

Sometimes when a person do a "Check In", but just some files the project dont know that the assembly must be included.

hope it helps.
