Question

I was working with normal connection until now and everything was smooth
but now I have switched to data entity model and with new connection string, I am having this error… How can i keep my entity string for my data manipulation and use the regular conn string only for login control?

Answer 1

Found the answer…
Just thought about it rationally and checked the config file
All I had to do was change the connectionStringName for provider tag

Just for future reference if someone runs into same problem
