After hours of searching online for some solution to get MySQL to work with Microsoft's WebSecurity, it doesn't. MySQL is not supported in Microsoft's WebSecurity SimpleMembership Authorization. :/
Bummer. I had to switch to Sql Sever in the end. I wasted a lot of time configuring EntityFramework to work with MySQL. Turns out, EF 6.0 does NOT support MySQL but EF 5.0 DOES.
Hopefully this question can save some people's time.
