Почему UserManager.CreateIdentityAsync () ищет IdentityRole и как исправить?

Вопрос

Я использую Identity2.0 с MVC5 CodeFirst. Я расширил как IdentityUser и IdentityRole следующим образом:

public class ApplicationUser : IdentityUser
{
    [Required]
    [StringLength(50)]
    public string FirstName { get; set; }

    [Required]
    [StringLength(50)]
    public string LastName { get; set; }
}

public class ApplicationRole : IdentityRole
{
    [Required]
    [StringLength(50)]
    public string ProperName { get; set; }

    [Required]
    public string Description { get; set; }
}

public class MyAppDb : IdentityDbContext<ApplicationUser, ApplicationRole, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>
{
    public MyAppDb()
        : base("MyAppDb")
    {
    }
}

Уведомление MyAppDb наследуется от IdentityDbContext но я MyAppDb ApplicationRole вместо IdentityRole . My ApplicationRole наследуется от IdentityRole поэтому это не должно быть проблемой.

НО...

Моя AccountController выбрасывает эту ошибку:

public class ApplicationUser : IdentityUser
{
    [Required]
    [StringLength(50)]
    public string FirstName { get; set; }

    [Required]
    [StringLength(50)]
    public string LastName { get; set; }
}

public class ApplicationRole : IdentityRole
{
    [Required]
    [StringLength(50)]
    public string ProperName { get; set; }

    [Required]
    public string Description { get; set; }
}

public class MyAppDb : IdentityDbContext<ApplicationUser, ApplicationRole, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>
{
    public MyAppDb()
        : base("MyAppDb")
    {
    }
}

В UserManager.CreateIdentityAsync(...) в этом коде:

public class ApplicationUser : IdentityUser
{
    [Required]
    [StringLength(50)]
    public string FirstName { get; set; }

    [Required]
    [StringLength(50)]
    public string LastName { get; set; }
}

public class ApplicationRole : IdentityRole
{
    [Required]
    [StringLength(50)]
    public string ProperName { get; set; }

    [Required]
    public string Description { get; set; }
}

public class MyAppDb : IdentityDbContext<ApplicationUser, ApplicationRole, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>
{
    public MyAppDb()
        : base("MyAppDb")
    {
    }
}

user создается здесь:

public class ApplicationUser : IdentityUser
{
    [Required]
    [StringLength(50)]
    public string FirstName { get; set; }

    [Required]
    [StringLength(50)]
    public string LastName { get; set; }
}

public class ApplicationRole : IdentityRole
{
    [Required]
    [StringLength(50)]
    public string ProperName { get; set; }

    [Required]
    public string Description { get; set; }
}

public class MyAppDb : IdentityDbContext<ApplicationUser, ApplicationRole, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>
{
    public MyAppDb()
        : base("MyAppDb")
    {
    }
}

Что такое «основная неисправность»? ;)

UPDATE: Я уверен, что проблема связана с UserStore здесь:

public class ApplicationUser : IdentityUser
{
    [Required]
    [StringLength(50)]
    public string FirstName { get; set; }

    [Required]
    [StringLength(50)]
    public string LastName { get; set; }
}

public class ApplicationRole : IdentityRole
{
    [Required]
    [StringLength(50)]
    public string ProperName { get; set; }

    [Required]
    public string Description { get; set; }
}

public class MyAppDb : IdentityDbContext<ApplicationUser, ApplicationRole, string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>
{
    public MyAppDb()
        : base("MyAppDb")
    {
    }
}

Как получить UserStore чтобы узнать об ApplicationRole когда я могу передать только один аргумент?

Принятый ответ

Я решил эту проблему, создав ApplicationUserStore и ApplicationUserManager :

public class ApplicationUser : IdentityUser<string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
    [Required]
    [StringLength(50)]
    public string FirstName { get; set; }

    [Required]
    [StringLength(50)]
    public string LastName { get; set; }

    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(ApplicationUserManager manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        return userIdentity;
    }

}

public class ApplicationUserLogin : IdentityUserLogin<string>
{
}

public class ApplicationUserClaim : IdentityUserClaim<string>
{
}

public class ApplicationUserRole : IdentityUserRole<string>
{
}

public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
{
    [Required]
    [StringLength(50)]
    public string ProperName { get; set; }
}


public class MyAppDb : IdentityDbContext<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
    public static MyAppDb Create()
    {
        return new MyAppDb();
    }

    public MyAppDb()
        : base("MyAppDb")
    {
    }
}


public class ApplicationUserStore : UserStore<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
    public ApplicationUserStore(MyAppDb context)
        : base(context)
    {
    }
}

public class ApplicationUserManager : UserManager<ApplicationUser, string>
{
    public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
        : base(store)
    {
    }

    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options)
    {
        var manager = new ApplicationUserManager(new ApplicationUserStore(new MyAppDb()));
        // Configure the application user manager
        manager.UserValidator = new UserValidator<ApplicationUser>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };
        manager.PasswordValidator = (IIdentityValidator<string>)new MinimumLengthValidator(8);

        return manager;
    }
}

public class ApplicationRoleStore : RoleStore<ApplicationRole, string, ApplicationUserRole>
{
    public ApplicationRoleStore(MyAppDb context)
        : base(context)
    {
    }
}

public class ApplicationRoleManager : RoleManager<ApplicationRole, string>
{
    public ApplicationRoleManager(IRoleStore<ApplicationRole, string> store)
        : base(store)
    {
    }

    public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options)
    {
        var manager = new ApplicationRoleManager(new ApplicationRoleStore(new MyAppDb()));

        return manager;
    }
}
