When I meet problem during using EF, the first thing I will do is to check the error information. Usually, the error information will give us useful tips. Then, if you are not familiar with this error information, you can search it on the Internet.
If I still can't solve this error, I will use breakpoint and
in VS to debug my project. Then using F10 to run the project step by step. I think this way is really useful. Hope my idea will help you.
