Whenever my MVC/”EF 4.1 code first” web application tries to access the data base for the first time it gives me the following exception:

After I refresh the page it works fine. But after every compilation/application unload, I get this exception for the first DB load.
I use MySql connector v6.4.3.0.
How can I solve that?
I think it’s fixed in MySQL connector v6.4.4.0.
