       BasicHttpBinding binding = new BasicHttpBinding();       EndpointAddress address = new EndpointAddress("http://localhost:8000/ChannelApp");       ChannelFactory<IRequestChannel> factory =       new ChannelFactory<IRequestChannel>(binding, address);       IRequestChannel channel = factory.CreateChannel();       channel.Open();       Message request = Message.CreateMessage(MessageVersion.Soap11, "hello");       Message reply = channel.Request(request);       Console.Out.WriteLine(reply.Headers.Action);       reply.Close();       channel.Close();       factory.Close();
