Question

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 。为什么它会挡住我的管？

问题：

我有一个非常简单的WCF应用程序。服务和客户端通过NetNamedPipe通信。但奇怪的是，有些机器可能是其他软件的原因，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，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)

Server stack trace:

这是我的代码'

----------------------------服务------------------ ------------

 using (var host = new ServiceHost(typeof(StringReverser), new[] { new Uri("net.pipe://localhost") }))
 {
     host.AddServiceEndpoint(typeof(IStringReverser), new NetNamedPipeBinding(), "PipeReverse");
     host.Open();

     Console.WriteLine("Service is available. Press <ENTER> to exit.");
     Console.ReadLine();

     host.Close();
  }

--------------------------客户端-------------------- -------------

var pipeFactory = new ChannelFactory<IStringReverser>(new NetNamedPipeBinding(), new EndpointAddress("net.pipe://localhost/PipeReverse"));
Console.WriteLine("pipeFactory Created. Press <Exit> to exit");
var pipeProxy = pipeFactory.CreateChannel();
Console.WriteLine("pipeProxy Created.");

while (true)
{
   var str = Console.ReadLine();
   Console.WriteLine("pipe: " + pipeProxy.ReverseString(str));
}

Answer 1

B1。该服务是Windows服务的主机，以管理员身份运行
B2。该服务，设置为net.pipe：// echonet作为他的地址
B3。我的服务，是自托管，以localuser身份运行

windowsservice＆gt; localuser 所以，namedpipe将重定向到该服务。

S1。停止服务
S2。更改我的服务主机，让它托管 windowsservice。

WCF-NetNamedPipe的ChannelFactory
