有两种通道来使用最新的网络通讯组件Indigo:typeed 和untyped,typed channel是通过Server端的WSDL,即通过自动自动生成的interface,很明显，我们要遵守一个契约。另一个方面，我们可以使用untyped channel,在这个通道里，我们只是从一端到另一端传递最基本的Message(Indigo中的最基本单元)，没有协议需要遵守，通常基于一个action URI.
看一个sample:

using System;

using System.MessageBus;

The client:

      class Client

      {

            [STAThread]

            static void Main(string[] args)

            {

Uri client = new Uri(String.Format("soap.tcp://{0}:6000/Client", System.Environment.MachineName));

Uri server = new Uri(String.Format("soap.tcp://{0}:6001/Server", System.Environment.MachineName));

                  Console.WriteLine("Client - {0}", client.ToString());

                  Uri action = new Uri("http://tempuri.org/action1");

                  Message message = new Message(action, "Hello");

                  message.Headers.Add(new PathHeader(server));

                  message.Headers.Add(new ToHeader(server));

                  message.Headers.Add(new ReplyInfoHeader(client));

                  Port port = new Port(client);

                  port.Open();

                  port.SendChannel.Send(message);

                  port.Close();

            }

      }

The Server:

      class Server

      {

            [STAThread]

            static void Main(string[] args)

            {

Uri server = new Uri(String.Format("soap.tcp://{0}:6001/Server", System.Environment.MachineName));

                  Port port = new Port(server);

                  ServerMessageHandler handler = new ServerMessageHandler();

                  port.ReceiveChannel.Handler = handler;

                  port.CloseTimeout = new TimeSpan(1, 0, 0, 0);

                  port.Open();

                  Console.WriteLine("Server - {0}", server.ToString());

                  Console.ReadLine();

            }

      }

      public class ServerMessageHandler : SyncMessageHandler

      {

            public override bool ProcessMessage(Message message)

            {

string content = message.Content.GetObject(typeof(string)) as string;

                  Console.WriteLine(content);

                  Console.ReadLine();

                  return true;     

            }

      }
看上去和remoting有点类似，其实编程方式更加简洁，更好理解。
