ApplicationUser IDの重要な負荷オブジェクト

Question

Identityを使用するC＃でアプリケーションを作成しています。私もUserManagerの作成

public class ApplicationUser: IdentityUser 
{ 
    public string Naam { get; set; } 
    public string Zipcode { get; set; } 
    public bool Active { get; set; } 
    public UserRole HighestRole { get; set; } 

    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager, string authenticationType) 
    { 
     // 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 async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> 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; 
    } 

} 

： は、私は自分のApplicationUser作成

public class UserManager : UserManager<Gebruiker> 
{ 
    public UserManager(IUserStore<Gebruiker> store) 
     : base(store) 
    { 
    } 

    public static UserManager Create(IdentityFactoryOptions<UserManager> options,IOwinContext context) 
    { 
     var manager = new UserManager(new UserStore<Gebruiker>(context.Get<ApplicationDbContext>())); 
     // Configure validation logic for usernames 
     manager.UserValidator = new UserValidator<Gebruiker>(manager) 
     { 
      AllowOnlyAlphanumericUserNames = false, 
      RequireUniqueEmail = true 
     }; 
     // Configure validation logic for passwords 
     manager.PasswordValidator = new PasswordValidator 
     { 
      RequiredLength = 6, 
      RequireNonLetterOrDigit = true, 
      RequireDigit = true, 
      RequireLowercase = true, 
      RequireUppercase = true, 
     }; 
     var dataProtectionProvider = options.DataProtectionProvider; 
     if (dataProtectionProvider != null) 
     { 
      manager.UserTokenProvider = 
       new DataProtectorTokenProvider<Gebruiker>(dataProtectionProvider.Create("ASP.NET Identity")); 
     } 
     return manager; 
    } 
} 

しかし、私は私のデータベースからユーザーを取得したい場合は、のUserRoleオブジェクトは常にnullです

これがデータベースからユーザーを引き出す方法です。

ApplicationUser user = UserManager.FindById(correctId); 

CODE：データベースに SAME TIME：
