Error in Connection String

If you are creating a DLL using #EntityFramework (EF Designer from database) be careful of your Connection String.

#Entity creates the connection string in DLL and it will compile perfectly. but when you import the DLL in a project never forget to reference the same connection string in project’s “App.config” file too, because at system startup, the DLL’s “App.config” file will be replaced by project’s “App.config” file.
