C# ASP.NET MVC:没有使用Ninject注册IUserTokenProvider

我在调用

\u userManager.generateemailconfimationtokenasync（user.Id）时遇到错误
没有注册IUserTokenProvider
正在生成要在帐户注册电子邮件中发送的令牌。我已经审阅了许多与此相关的帖子，但没有一篇能够解决我的问题。据我所知，此功能通过以下方式连接到
ApplicationUserManager
类中：

if (dataProtectionProvider != null)
{
    IDataProtector dataProtector = dataProtectionProvider.Create("ASP.NET Identity");

    this.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(dataProtector);
}

但是，绑定似乎不起作用，因为my
ApplicationUserTokenProvider
的
UserTokenProvider在生成我的令牌时仍然为空。作为参考，您可以在下面找到my
ApplicationUserManager的代码：

public class ApplicationUserManager : UserManager<ApplicationUser>
  {
    public ApplicationUserManager(IUserStore<ApplicationUser> store, IDataProtectionProvider dataProtectionProvider)
        : base(store)
    {
      // Configure validation logic for usernames
      this.UserValidator = new UserValidator<ApplicationUser>(this)
      {
        AllowOnlyAlphanumericUserNames = false,
        RequireUniqueEmail = true
      };

      // Configure validation logic for passwords
      this.PasswordValidator = new PasswordValidator
      {
        RequiredLength = 6,
        RequireNonLetterOrDigit = true,
        RequireDigit = true,
        RequireLowercase = true,
        RequireUppercase = true,
      };

      // Configure user lockout defaults
      this.UserLockoutEnabledByDefault = true;
      this.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
      this.MaxFailedAccessAttemptsBeforeLockout = 5;

      // Register two factor authentication providers. This application uses Phone and Emails as a step of receiving a code for verifying the user
      // You can write your own provider and plug it in here.
      this.RegisterTwoFactorProvider("Phone Code", new PhoneNumberTokenProvider<ApplicationUser>
      {
        MessageFormat = "Your security code is {0}"
      });
      this.RegisterTwoFactorProvider("Email Code", new EmailTokenProvider<ApplicationUser>
      {
        Subject = "Security Code",
        BodyFormat = "Your security code is {0}"
      });
      this.EmailService = new EmailService();
      this.SmsService = new SmsService();

      if (dataProtectionProvider != null)
      {
        IDataProtector dataProtector = dataProtectionProvider.Create("ASP.NET Identity");

        this.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(dataProtector);
      }
    }
  }

});

});

if（dataProtectionProvider！=null）
{
IDataProtector dataProtector=dataProtectionProvider.Create（“ASP.NET标识”）；
this.UserTokenProvider=新的dataProtector TokenProvider（dataProtector）；
}
}
}

非常感谢您的帮助。
清洁并构建解决方案后，问题已得到解决。请注意，在问题发生期间，解决方案已构建多次，但未清理。
是否有帮助？IDataProtectionProvider被注入我的
ApplicationUserManager
中，此IDataProtectionProvider通过构造函数
IDataProtector中的以下两行提供
IUserTokenProvider
dataProtector=dataProtectionProvider.Create（“ASP.NET标识”）
和
this.UserTokenProvider=newdataprotectortokenprovider（dataProtector）。绑定在Startup.cs中注册为
kernel.Bind（）.ToMethod（x=>\u app.GetDataProtectionProvider（））
@mjwills不幸的是，我已经多次查看了这两篇文章，我试图使用它们的解决方案，但都没有效果
