nservicebus加载双订阅

我的ICommand处理程序被调用两次！
我在IIS中自我托管nservicebus（并使用卡西尼进行调试）。nservicebus加载双订阅

 Configure.ScaleOut(_ => _.UseSingleBrokerQueue()); 
     Configure.With() 
      .AutofacBuilder(container) 
      .InMemorySubscriptionStorage() 
      .UseInMemoryTimeoutPersister()     
      .UseTransport<SqlServer>("myconnectionstring") 
      .UnicastBus() 
      .PurgeOnStartup(true) 
      .CreateBus() 
      .Start(() => Configure.Instance.ForInstallationOn<Windows>().Install());

下面是在SQL服务器的消息标题[审计]表启动之后，有两个订阅同一事件的处理程序？

我与ICommand处理器遇到了同样的问题，它是在响应被称为两次到bus.Send(new CommandInstance())

我有在组装一个特定的命令一个命令处理程序。它被称为两次。

该事件被调用两次

/// <summary> 
/// The balance captured handler. 
/// </summary> 
public class BalanceCapturedEvt : IHandleMessages<IBalanceCapturedEvent> 
{ 
    ... 
}

事件处理程序是否托管在同一端点上（自托管的IIS）？ –

是的，它在同一个进程中托管。 – Jim

该命令似乎也会被触发不止一次，即使它是完全不同的界面。 – Jim

我的结论必须是NServiceBus不工作以及相当自我主办。我还没有找到这方面的补救措施，并得出结论，它'不可能。
