Hangfire處理定義為SingleInstance的autofac依賴項

Question

在ASP.NET應用程序中將hangfire 1.3.4與hangfire.autofac 1.0.0一起使用。 我有以下情況：

 class MyType : IDisposable 
 {
      public void Start()
      {
          RecurringJob.AddOrUpdate("background-update", () => ProcessData(), Cron.Daily());
          RecurringJob.Trigger("background-update"); 
      }

     public void ProcessData(){...}

     public void Dispose(){...} 
 }
 ...
 var builder = new ContainerBuilder();
 builder.RegisterType<MyType>().SingleInstance();
 var cont = builder.Build();
 app.UseHangfire(config =>
        {
            var options = new SqlServerStorageOptions();
            config.UseAutofacActivator(cont);
            config.UseSqlServerStorage("MyServer", options);
            config.UseServer();
        });

...
var c = cont.Resolve<MyType>();
c.Start();

我看到的是Autofac根據請求執行了周期性作業，但隨后處理了MyType實例，這顯然會導致后續調用失敗，因為它被定義為單例，應該在關機時由Autofac處置。

我是否缺少某些東西或這是一個錯誤？

這是調用棧：
