Question

I am trying to create a web app using ASP.Net MVC3, Entity Framework and MySQL.

I have added the following code to my Web.Config file.

Answer 1

Even though this is answered, but I have experienced the same problem and my in case it was in the connection string; I had the part "Integrated Security" when I really shouldn't have used it; I was relying on the database authentication.

I removed the "Integrated Security=True" part and it worked perfectly :)
