The provider did not return a ProviderManifestToken string error

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

May be the error is in your connection string. Have you tried to connect to your DB instance using the above log in. try changing the connection string

connectionString="Data Source=.;Initial Catalog=contacts;Integrated Security=True uid=root;pwd=password;" providerName="MySql.Data.MySqlClient"/>

use above if you are using sql server, else if you are using sql express use below one

 connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=contacts;Integrated Security=True uid=root;pwd=password;" providerName="MySql.Data.MySqlClient"/>

Answer 2

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 :)
