I\'m currently building a new ASP.NET MVC 5 project which I want to release around September. I need to choose a membership system, but I\'m currently quite confused about which
I would advise against using SimpleMembership as well. You can still use int IDs in your database, you would just need to ToString() the ID when plugging in your database entity, i.e.:
public class MyUser : IUser {
[Key]
int UserID { get; set; }
string IUser.Id { get { return UserId.ToString(); } }
}
