MVC4 UserProfiles has no results after logging in

问题

On the new MVC4 it uses SimpleMembership which when logging in contains the line:

if (ModelState.IsValid && WebSecurity.Login(model.UserName, model.Password, persistCookie: model.RememberMe))

After this I did the following to get the extended properties I applied to the UserProfile:

var context = new UsersContext();
var user = context.UserProfiles.First(n => n.UserName == model.UserName);

But UserProfiles has no results and has a count of 0 from context??? There must be something in there as I'm logging in with a user?
