更新 20121214 咨询冲突服务的开发者，他们使用net.pipe://echonet作为服务地址，并使用DuplexChannelFactory。为什么它会阻塞我的管道？
问题：
我有一个非常简单的 WCF 应用程序。Service 和 Client 通过 NetNamedPipe 通信。但奇怪的是，有些机器可能是因为其他软件的原因，导致ChannelFactory开始调用Service，抛出异常：System.ServiceModel.ProtocolException。
我怎么知道哪个应用程序捕获了我的 WCF 消息，以及我应该如何避免这个问题。
这是例外：
System.ServiceModel.ProtocolException: The requested upgrade is not supported by 'net.pipe://localhost/xxxx/xxxx'. This could be due to mismatched bindings (for example security enabled on the client and not on the server)
