Hangfire后台作业仍然排队

Question

我有一个MVC应用程序，正在尝试使用Hangfire和邮政发送电子邮件。该电子邮件必须在注册后发送。注册工作正常，但是我运行的作业仍然排队，并且我没有收到任何电子邮件。所以在我的MVC控制器中，我有以下代码：

public async Task<ActionResult> Register(RegisterViewModel model)
{
    //register correctly the user

    //I send the email
    BackgroundJob.Enqueue(() => 
        NotifyRegistration(user.Id, user.UserName, user.Email)   
    );

    ...
 }

[AutomaticRetry(Attempts = 5)]
public async Task NotifyRegistration(string userId, string username, string email)
{
    //I calculate callbackUrl

    var viewsPath = Path.GetFullPath(HostingEnvironment.MapPath(@"~/Views/Emails"));
    var engines = new ViewEngineCollection();
    engines.Add(new FileSystemRazorViewEngine(viewsPath));

    var emailService = new EmailService(engines);

    var emailToSend = new NewRegisteredUserEmail
    {
        To = email, UserName = username, CallbackUrl = callbackUrl 
    };

    emailService.Send(emailToSend);
}

我无法调试NotifyRegistration方法。我不知道为什么 我正在使用邮政，所以EmailService不是我的实现。这里是我如何配置smtp服务：

<system.net>
  <mailSettings>
    <smtp deliveryMethod="Network">
      <network host="smtp.live.com" port="25" enableSsl="true" userName="***" password="***"></network>
    </smtp>
  </mailSettings>
</system.net>

如果我运行hangfire仪表板，我看到工作已入队

但是没有其他事情发生。我错过了什么发送电子邮件？

谢谢

更新 在startup.cs中，我这样写：

var options = new SqlServerStorageOptions
{
    QueuePollInterval = TimeSpan.FromSeconds(1)
};

GlobalConfiguration.Configuration
     .UseSqlServerStorage("DbConnectionString", options)
     .UseFilter(new LogEmailFailureAttribute());

 app.UseHangfireDashboard();
 app.UseHangfireServer();

更新2 我以这种方式转换了NotifyRegistration：

[AutomaticRetry(Attempts = 5)]
public async Task NotifyRegistration(string userId, string username, string email, EmailService emailService)
{
    //I calculate callbackUrl

    var emailToSend = new NewRegisteredUserEmail
    {
        To = email, UserName = username, CallbackUrl = callbackUrl 
    };

    emailService.Send(emailToSend);
}

我发现了问题：

1. 不支持sql server版本。我使用的是2005。支持的数据库是2008R2及更高版本：http : //docs.hangfire.io/zh-CN/latest/configuration/using-sql-server.html

2. 方法NotifyRegistration必须是静态的：https ://discuss.hangfire.io/t/jobs-in-enqueue-state-most-never-run/2367/4

。

[AutomaticRetry(Attempts = 5)]
public static void NotifyRegistration(string userId, string username, string email, EmailService emailService)
{
    //I calculate callbackUrl

    var emailToSend = new NewRegisteredUserEmail
    {
        To = email, UserName = username, CallbackUrl = callbackUrl 
    };

    emailService.Send(emailToSend);
}
