Azure服务总线超时异常与NancyFX

我有一个NancyFX API，当其中一个端点被命中时，我需要启动一个与端点本身解耦的长时间运行的异步任务。所以我尝试使用Azure Service Bus队列。

当NancyFX端点被击中时，我成功地将消息写入队列。我还可以成功地从NancyFX以外的其他地方订阅和读取队列(我在Linqpad上进行了测试)。

但是，如果我尝试从NancyFX应用程序订阅，我会在启动应用程序的一秒钟或两秒钟内获得超时异常。我正在另一个线程中执行此操作，该线程从NancyFX Bootstrapper.ApplicationStartup覆盖中启动。

我不确定为什么这与在NancyFX应用程序中不这样做不同。我在web.config文件中看不到任何相关的东西。

下面是我用来订阅队列的代码…

var tokenProvider = TokenProvider.CreateSharedAccessSignatureTokenProvider("Main", AccessKey);
var factory = await MessagingFactory.CreateAsync("sb://myapp.servicebus.windows.net", tokenProvider);
var receiver = await factory.CreateMessageReceiverAsync("MyQueue");
receiver.OnMessage(bm =>
{
    // Do something here
}, new OnMessageOptions
{
    MaxConcurrentCalls = 1,
});

下面是例外…

System.ServiceModel.FaultException ' 1 [System.ServiceModel。ExceptionDetail]:操作超时。b6b8e25a-714f-4f55-8a79-91e390f47a96_G25 (Fault Detail等于一个ExceptionDetail，可能由IncludeExceptionDetailInFaults=true创建，其值为:系统。TimeoutException:操作超时。) .

当我在调试器中捕获它时，这里是调用堆栈…
