I am trying to run my tests on TeamCity which is currently installed on my machine.

System.InvalidOperationException: System.InvalidOperationException:

The Entity Framework provider type ‘System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' for the ‘System.Data.SqlClient‘ ADO.NET provider could not be loaded. Make sure the provider assembly is available to the running application.

See http://go.microsoft.com/fwlink/?LinkId=260882 for more information..

I have no reference to System.Data.Entity in any of my projects as was suggested on codeplex for upgrading to EF6.

So, I am not sure why am I getting this exception. I do not get any such exception when I run the tests from VS.

I did try to set CopyLocal to false then again to true.. but that does not seem to work either.

Update

My app.config has the following . Does this cause some behavior that I don’t understand ?

I get the following stacktrace in teamcity .
