与 Web 角色进行内部 tcp 连接后，Azure 辅助角色变得无响应

Question

我发布了首先出现的问题 这里因为它似乎在微软论坛上已经死了。另外，Stack Overflow 更好。 :-P

我在 Azure 上以辅助角色托管 TCP 端点 -

var _breadcrumbServiceHost = new ServiceHost(typeof(BreadcrumbService));
var binding = new NetTcpBinding(SecurityMode.None);
var externalEndPoint = RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["shuttles"];
_breadcrumbServiceHost.AddServiceEndpoint(typeof(IBreadcrumbService), binding, String.Format("net.tcp://{0}/BreadcrumbService", externalEndPoint.IPEndpoint));

我收到两个抛出的异常 -

System.InvalidProgramException  -  Common Language Runtime detected an invalid program

而且

Unhandled exception: System.Runtime.CallbackException: Async Callback threw an exception. ---> System.InvalidProgramException: Common Language Runtime detected an invalid program.
   at System.ServiceModel.Dispatcher.ErrorBehavior.HandleErrorCommon(Exception error, ErrorHandlerFaultInfo& faultInfo)
   at System.ServiceModel.Dispatcher.ChannelDispatcher.HandleError(Exception error, ErrorHandlerFaultInfo& faultInfo)
   at System.ServiceModel.Dispatcher.ChannelDispatcher.HandleError(Exception error)
   at System.ServiceModel.Dispatcher.ErrorHandlingReceiver.EndTryReceive(IAsyncResult result, RequestContext& requestContext)
   at System.ServiceModel.Dispatcher.ChannelHandler.EndTryReceive(IAsyncResult result, RequestContext& requestContext)
   at System.ServiceModel.Dispatcher.ChannelHandler.AsyncMessagePump(IAsyncResult result)
   at System.Runtime.Fx.AsyncThunk.UnhandledExceptionFrame(IAsyncResult result)
   at System.Runtime.AsyncResult.Complete(Boolean completedSynchronously)

这种情况并不总是发生 - 有时 Azure 非常高兴。

帮助！！谢谢。

解决了！工作线程和 IntelliTrace 中托管的 WCF 似乎存在问题。禁用 IntelliTrace 解决了这个问题。
