Tests that use Fakes/Shims fail on server, but succeed in local

Tests that use Fakes/Shims fail on build server, but succeed in local.

This following error is gone when I remove the test that uses shims. Do I need to do any specific configuration on build server? On a side note, I'm using shims in my specflow test cases.
