WCF-NetNamedPipe's ChannelFactory

Question

Update 20121214 consultation with the developers of the conflict service, they use net.pipe://echonet as service address, and use DuplexChannelFactory. why it will block my Pipe?

---

Question:

I have a very simple WCF application. Service and Client through NetNamedPipe communication. But it is strange , some machines may be the reason because other software, resulting in the ChannelFactory began to call the Service, throw an exception : System.ServiceModel.ProtocolException .

How could I know which application catch my WCF message, and how should I avoid this problem.

here is exception:

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)

here is my code'

----------------------------Service------------------------------

 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();
  }

--------------------------Client---------------------------------

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. the service, is host on windowsservice,run as administrator
• b2. the service, is set net.pipe://echonet as his address
• b3. my service, is self host,run as localuser

windowsservice > localuser so, namedpipe will redirect to the service.

• s1. stop the service
• s2. change my service host, let it host on windowsservice.
