Answer 1

Why are you still using the CTP? The release has been out for quite some time. Upgrade, then see if your problem persists. It may be a fixed problem.

Answer 2

The stack trace points out that there is a problem with your connection string.
Fix your connection string, and the problem should dissapear.
