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

Restarting the computer worked for me.

While this message was showing, I did not find any differences between my computer [Windows 10] and the test server where the the application was deployed with the same configuration and was working correctly there and using the same database. It means the issue was probably not connected to the database running on the test server.

Worth mentioning is there were some Windows updates pending while restarting.
