wcf step by step之HelloWorld

数据契约
[DataContract]
    public class Employee
    {
        [DataMember]
        public int ID;

        [DataMember]
        public string Name;
    }

操作契约
[ServiceContract]
    public interface IEmployeeService
    {
        [OperationContract]
        void AddEmployee(Employee emp);

        [OperationContract]
        string GetEmployeeNameByID(int id);
    }

服务与EndPoint绑定
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="HelloWorldWCF.EmployeeService" behaviorConfiguration="basicHttpBinding_EmployeeService">
        <endpoint address="" binding="basicHttpBinding" contract="HelloWorldWCF.IEmployeeService"></endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="basicHttpBinding_EmployeeService">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

为什么叫做Hello world程序，因为客户通过点add service reference来添加服务，vs自动帮你生成服务端的代理类和配置文件，就像web service的调用一样简单吧。
