Working with VS 2012 + MVC4 + EF5 trying to add controller with Context fails when connectionstring configSource in place with Error :

"Unable to retrieve metadata for MvcTestApp.Models.DummyClass. Unable to open configSource file 'connections.config'.

BTW: The path is correct the application actually runs correctly.

Does Visual Studio 2012 EF5 support connectionStrings configSource to be in a separated file at design time ? or no way during development !!!

Thanks for your feedback.

I have the same problem. I solved it putting a copy of 'connections.config' in 

C:\Users\[CurrentUser]\AppData\Local\Temp.

Hope this help you.

    +1, but I don't know if I should be sad or happy that this is the solution. How much does Visual Studio cost? yet it can't even find the configSource defined in the config. Tut tut. – Neil Thompson Feb 12 '14 at 13:11
  • @NeilThompson Thank you for your point. I searched for a solution of the "problem" just because... In fact, I think that during development there are no reason for this approach - external configSource. – George Feb 15 '14 at 17:36
