title: How to sign in with "E-Mail" instead of "UserName" in ASP.NET MVC 4 Simple Membership
body: <p>I am developing an entry level application with ASP.NET MVC 4. The application will have a membership system. I want to use integrated SimpleMembershipProvider because creating a new one will be complex for me. So the users must log in to application with their e-mail adresses instead of user name as in SimpleMembershipProvider. But I couldn't make this change. Is the only way to do this is creating my own membership provider?</p>
