WCF的执行过程
既然是实现互通信。那么肯定会有概念意义上的服务端Server 和概念意义上的客户端 Client，在这里，我所说明的都是概念意义上的，单独强调此，是因为，基于WCF的通信没有物理上的划分，但是概念上肯定有边界。原因：
1 WCF可以host(承载)在 WAS 基于Web的方式激活，也可以承载在Winform程序， Windows服务（本质就是无窗口的窗体程序），WPF程序 ， 控制台程序（自承载），传统意义上 的CS架构。物理界限分明，服务端就是服务端，客户端调用发送请求到服务端。WCF这种不强制承载环境，多通信协议的三炮，彻底打乱了保守的三观。
以下是一个控制台承载的服务............
class Program
{
public static void Main()
{
ServiceHost host = new ServiceHost(typeof(MyCalculator));
host.Open();
//Can do blocking calls:
Console.WriteLine("Press ENTER to shut down service.");
Console.ReadLine();
host.Close();
}
}
配置文件：
无语了 ，太长了，一会儿在下面自己下载去.............

可见 ，这厮没有物理意义上的界限，同样，你也可以讲服务承载在你的客户端程序Winform中，当程序启动的时候，启动服务，然后就可以在程序间进行服务数据的传播。
好，说了一大堆废话，我们看看，这东西的执行过程吧。计算机世界中的东西都是按照流程走的，即使多线程并发 多进程，在CPU的世界永远都要排队执行，只不过丫执行太快，给人的幻觉是同时进行。。。。。。。
（看下面的时候：大家必须着重理解 通道通信，拦截分发，终结点的概念）

WCF体系架构是基于一种拦截机制来实现的，负责传递和拦截消息的组件为通道，在客户端发出对服务端服务的调用时，首先会通过一个服务代理对象，将调用方提供的对象序列化到消息中，然后该消息则通过通道进行传递。通道不只是包括一个，而是多个通道对消息进行处理，包括传输、消息编码、管理会话、传播事务等，但最底层的通道总是传输通道。这些通道的构成形成了一个通道堆栈。由于对象已经被序列化，因而此时通道传递的消息可以跨进程或机器进行传递，利用传输通道传递到服务端。服务端的构成与客户端基本相似，仍然是通过通道栈中最底层的传输通道接收消息，然后解析消息编码，并一层层地往上传输。在服务端的通道栈之上，则是一个分发器（Dispatcher，或者说是调度器），它会首先对消息进行检查，然后选择一个客户端要调用的操作。在这个过程中，消息会被反序列化。
以下是执行过程的代码：
