1. You have done something bad.
2. We would have no idea. You need to debug your program.
3. That depends on what you find from your debugging.

Based on what you've provided, it's impossible to answer your question. You need to look at the InnerException of that exception to see the real error messages which were probably thrown by Entity Framework.

That's useless. I said you need the INNEREXCEPTION of that exception. There's possibly more exceptions buried inside these exceptions.
