User.IsInRole failing after migrating SimpleMembership database to Identity 2

问题

I successfully updated my application from MVC4-EF5 to MVC5-EF6.

I then migrated my database from Simplemebership to Identity 2.0.

I can login but User.IsInRole always returns false. All the proper tables AspNetUsers, AspNetRoles, AspNetUserRoles, AspNetLogins and AspNetClaims have been created, the spelling and type of all columns are correct and they have been populated with the data from the SimpleMembership tables (which have been deleted).

I have a user "MyUser" which is Id = 2 in the AspNetUsers table and a role "XYZ" which is Id = 2 in the AspNetRoles table and User 2 is mapped to Role 2 in the AspNetUserRoles table.

When logged in as "MyUser"

var user = _db.Users.SingleOrDefault(u => u.UserName == User.Identity.Name);
user does get set to "MyUser" but

User.IsInRole("XYZ") returns false.

I added a test variable, var testrole = Roles.GetRolesForUser();, when testrole is examined in debug it returns an empty string array {string[0]}. Running User.IsInRole("XYZ") from the Immediate Window returns false.

I've read through every document I can find on Identity, Identity 2.0 and migrating from SimpleMembership and Identity 1.0 and I can't find any implementation requirements (beyond what I've done in my posted code) that I have missed to make Identity work (and it is working at some level since then login works).

I have used Identity 2.0's extensibility hook to implement INT for my Primary keys.

WebSecConfig.cs: (called from Global.asax.cs) (removed this code for UPDATE: 1)

using WebMatrix.WebData;

namespace MyApplication
{ 
  public static class WebSecConfig
  {
    public static void RegisterWebSec()
    {
      WebSecurity.InitializeDatabaseConnection 
        ("MyApplication", "AspNetUsers", "Id", "UserName", autoCreateTables: true);
    }
  }
}

ApplicationUser:

  public class ApplicationUser : IdentityUser<int, CustomUserLogin, CustomUserRole, CustomUserClaim>
  { 
    [StringLength(15)]
    public new string UserName { get; set; }
    public int AcId { get; set; }
    public int LcId { get; set; }
  }

  public class CustomRole : IdentityRole<int, CustomUserRole>
  {
    public CustomRole() { }
    public CustomRole(string name) { Name = name; }
  }

  public class CustomUserRole : IdentityUserRole<int> { }
  public class CustomUserClaim : IdentityUserClaim<int> { }
  public class CustomUserLogin : IdentityUserLogin<int> { }

IdentityDbContext:

  public class MyDb : IdentityDbContext<ApplicationUser, CustomRole, int, CustomUserLogin, CustomUserRole, CustomUserClaim>
  {
    public MyDb() : base("MyApplication") { }

    // public virtual DbSet<UserProfiles> Users { get; set; }
    public virtual DbSet<MyTable> MyTables { get; set; } // properties marked virtual for Mocking override
    ...

  protected override void OnModelCreating(DbModelBuilder modelBuilder)
  {
    base.OnModelCreating(modelBuilder);
    modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
  }

Account Controller:

  [RequireHttps]
  [Authorize]
  public class AccountController : Controller
  {
    private readonly IUserService _userService;

    public UserManager<ApplicationUser, int> UserManager { get; private set; }

    public AccountController() 
    : this(new UserService(), new UserManager<ApplicationUser, int>(new UserStore<ApplicationUser, CustomRole, int, CustomUserLogin, CustomUserRole, CustomUserClaim>new MyDb()))) { } 

    public AccountController(IUserService userService, UserManager<ApplicationUser, int> userManager)
    { _userService = userService; UserManager = userManager; }

    // GET: /Account/Login
    [AllowAnonymous]
    public ActionResult Login() { return View(); }

    // POST: /Account/Login
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult Login(LoginVm vM)
    { 
      if (ModelState.IsValid) 
      { 
        var user = UserManager.Find(vM.UserName, vM.Password);
        if (user != null)
        { 
          FormsAuthentication.SetAuthCookie(user.UserName, false);
          return RedirectToAction("UserRouting", "Home");
        }
      } 
      ModelState.AddModelError("", "The user name or password provided is incorrect.");

      return View(vM);
    }

Home Controller:

using System;
using System.Web.Mvc;
using MyApplication.Models;
using System.Linq;
using System.Web.Security;

namespace MyApplication.Controllers
{
  [Authorize]
  public class HomeController : Controller
  {
    private readonly MyDb _db = new MyDb(); 

    public ActionResult UserRouting()
    {
      var user = _db.Users.SingleOrDefault(u => u.UserName == User.Identity.Name);
      var testrole = Roles.GetRolesForUser();  // for testing, remove from production
      if (User.IsInRole("XYZ")) { // mycode }
      ...
     }
  }

Have I missed something on configuring Identity 2.0 or is this a bug in Identity 2.0?

UPDATE 1: Removed the Global.asax.cs call to WebSecConfig. This had been masking a different issue with User.IsInRole.

Set breakpoint on var user in Home Controller UserRouting Action
Run app in debug and login in as "MyUser".
Step in and user gets set to "MyUser".
Step into var testrole and it throws 'Object reference not set to an instance of an object.'

Re-start and login again as "MyUser".
Step in and user gets set to "MyUser".
From Immediate Window enter User.IsInRole("XYZ") and it returns:

A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll
A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll
A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll
A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll
A first chance exception of type 'System.Web.HttpException' occurred in System.Web.dll
A first chance exception of type 'System.Web.HttpException' occurred in System.Web.dll
A first chance exception of type 'System.Web.HttpException' occurred in System.Web.dll

And opens a Warning dialogue box with:

HttpException was unhandled  
An unhandled exception of type 'System.Web.HttpException" occurred in System.Web.dll
Additional information: Unable to connect to SQL Server database.

My basic Database setup is correct or I wouldn't have been able to login. This leads me to believe there is a small discrepancy in how I ran the migration. Does anyone have an idea where I tripped up.

UPDATE 2: I refactored the code and migration script to use the default nvarchar for the Primary Keys and got the same results as Update 1.

UPDATE 3:

I needed to add <remove name="RoleManager" /> to the node as part of the MVC4-MVC5 migration, which I have now done.

Now I'm back to my original problem. User.IsInRole always returns false. If I run User.IsAuthenticated from the Immediate Window it returns

'System.Security.Principal.IPrincipal' does not contain a definition for 'IsAuthenticated' and no extension method 'IsAuthenticated' accepting a first argument of type 'System.Security.Principal.IPrincipal' could be found (are you missing a using directive or an assembly reference?)

I was able to get Identity.UserManager.IsInRole to work.

Home Controller: (revised to use UserManager)

using System;
using System.Web.Mvc;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
using MyApplication.Models;
using System.Linq;
//using System.Web.Security;

namespace MyApplication.Controllers
{
  [Authorize]
  public class HomeController : Controller
  {
    private readonly MyDb _db = new MyDb();
    public UserManager<ApplicationUser> UserManager { get; private set; }
    public HomeController()  
      : this(new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new MyDb()))) { }
    public HomeController(UserManager<ApplicationUser> userManager)  
    { UserManager = userManager; }

    public ActionResult UserRouting()
    {
      var user = _db.Users.SingleOrDefault(u => u.UserName == User.Identity.Name);
      //var testrole = Roles.GetRolesForUser();  // for testing, remove from production
      if (UserManager.IsInRole(user.Id, "XYZ")) { // mycode }
      ...
     }
  }

This indicates that my database migration was correct.

I have dozens of calls to User.IsInRole in Controllers, Views, Custom Attributes, methods and classes in my app. To my understanding User.IsInRole is still a valid method in MVC5-EF6. If it is still considered a valid method rather than having to do a major refactoring of this legacy app I pose again my original question "why is User.IsInRole failing after SimpleMembership to Identity 2.0 migration"?

I've tested User.IsInRole in an Identity 1.0 MVC app and it works. I updated the app to Identity 2.0 and it still works. So I think it is safe to say that User.IsInRole is supported with Identity 2.0.

回答1:

After further investigation I found the problem to be that I never successfully logged in and since the User wasn't authenticated it caused the User.IsInRole to fail.

   var user = UserManager.Find(vM.UserName, vM.Password);

When you examine user in debug "MyUser" has been found but if you drill down further you find UserName is set to null.

                    UserName            null        string

In ApplicationUser I overrode the UserName.

[StringLength(15)]
public new string UserName { get; set; }

When I removed the UserName override everything started working (I left UserName as a nvarchar(15), not null). The UserName override in ApplicationUser was the problem. If you want to change the nvarchar sizes you apparently just need to do that in the migration script.

Migrations from SimpleMembrship to Identity 2.0 works. User.IsInRole also works with Identity 2.0.
