ASP.NET 4 Membeship schema changed - asp.net-mvc

Question

I've installed yesterday Visual Studio 2012 (RTM, via mytt DreamSpark account) and created a demo MVC site (using .NET 4.0 since I wish it to be supported on Azure).
I've started to investigate the project and in addition to built-in option to use external services (Facebook, Twitter, Windows Live and Google) I've found out that the entire membership schema has been changed:
The new structure contains 4 tables (the UserProfile is a first-code approch Entity Framework table).
Note that although the tables prefix is "webpages_" its a proper MVC 4 site.
I've opened the AccountModels.cs file and saw that it has been changed too:
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity;
using System.Globalization;
using System.Web.Mvc;
using System.Web.Security;
namespace MyGuestbook.Models
{
public class UsersContext : DbContext
{
public UsersContext()
: base("DefaultConnection")
{
}
public DbSet<UserProfile> UserProfiles { get; set; }
}
[Table("UserProfile")]
public class UserProfile
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }
public string UserName { get; set; }
}
public class RegisterExternalLoginModel
{
[Required]
[Display(Name = "User name")]
public string UserName { get; set; }
public string ExternalLoginData { get; set; }
}
public class LocalPasswordModel
{
[Required]
[DataType(DataType.Password)]
[Display(Name = "Current password")]
public string OldPassword { get; set; }
[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "New password")]
public string NewPassword { get; set; }
[DataType(DataType.Password)]
[Display(Name = "Confirm new password")]
[Compare("NewPassword", ErrorMessage = "The new password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }
}
public class LoginModel
{
[Required]
[Display(Name = "User name")]
public string UserName { get; set; }
[Required]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[Display(Name = "Remember me?")]
public bool RememberMe { get; set; }
}
public class RegisterModel
{
[Required]
[Display(Name = "User name")]
public string UserName { get; set; }
[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }
}
public class ExternalLogin
{
public string Provider { get; set; }
public string ProviderDisplayName { get; set; }
public string ProviderUserId { get; set; }
}
}
So I would like to ask:
- Does this the new users structure (that is generated from asp_regsql.exe) or this is a template-specific structure?
- Does somebody have any documentation about the new structure and how to integrate with it?
- Does anybody know how one can migrate an "older" project (e.g. MVC 3 project) with the old structure to the new one?
Thanks! :)

Answer 1

I've found some article that answer my question.
Edit:
Why the sudden changes:
The changes has been made because Microsoft has changed the default ASP.NET MVC 4 template.
The standard "Internet Application" template which gives default accounts management has been changed and now using the WebMatrix 2 helpers.
The AccountController has been totally rewritten in order to use SimpleMembership class which supports the third-party integration and gives us the ability to use Entity Framework code-first approach.
Usage of old membership providers
As long as I've read, because the SimpleMembership class using ExtendedMembershipProvider you cannot use the default universal providers and must use the built-in provider OR creating an ExtendedMembershipProvider custom provider.
More information can be found here:
