entity exception was unhandled by user code
text/html 11/5/2010 6:51:32 PM BrunoTerkaly 0. Getting error. Entity Exception was unhandled by user code. The underlying provider failed on open. The code fails when executed from within a SL â enabled WCF Service. The problem is not connection string. I do have a connection string in the web project. This code did work on my other computer.
