Question

在ASP.NET应用程序中使用hangfire 1.3.4和hangfire.autofac 1.0.0。我有以下情况：

 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Autofac按要求执行循环作业，但随后处理MyType实例，这显然会导致后续调用失败，因为它被定义为单例，并且应该在关闭时由Autofac处理掉。

我错过了什么或这是一个错误吗？

这是callstack：

最新（beta）版本的hangfire修复了此问题，详见https://github.com/HangfireIO/Hangfire/issues/329。

Hangfire处理autofac依赖项，定义为SingleInstance
