Follow artech to learn about the status of WCF (3)

At first, I thought it was a problem with the WCF session. I knocked on one side of the code and found that the session was not used to store data. After my own research, I found that the author again stored the status of the WCF.

The project structure is as follows:

 

The Code is as follows:

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ServiceModel;using Contract;namespace Client{    class Program    {        static void Main(string[] args)        {            ChannelFactory<ICalculator> calculatorChannelFactory = new ChannelFactory<ICalculator>("httpEndpoint");            Console.WriteLine("Create a calculator proxy: proxy1");            ICalculator proxy1 = calculatorChannelFactory.CreateChannel();            Console.WriteLine("Invocate  proxy1.Adds(1)");            proxy1.Adds(1);            Console.WriteLine("Invocate  proxy1.Adds(2)");            proxy1.Adds(2);            Console.WriteLine("The result return via proxy1.GetResult() is : {0}", proxy1.GetResult());            try            {                proxy1.Adds(1);            }            catch (Exception ex)            {                Console.WriteLine("It is fail to invocate the Add after terminating session because \"{0}\"", ex.Message);            }            //(proxy1 as ICommunicationObject).Close();            Console.WriteLine("Create a calculator proxy: proxy2");            ICalculator proxy2 = calculatorChannelFactory.CreateChannel();            Console.WriteLine("Invocate  proxy2.Adds(1)");            proxy2.Adds(1);            Console.WriteLine("Invocate  proxy2.Adds(2)");            proxy2.Adds(2);            Console.WriteLine("The result return via proxy2.GetResult() is : {0}", proxy2.GetResult());            //(proxy2 as ICommunicationObject).Close();            Console.Read();        }    }}

The server configuration is as follows:

  <system.serviceModel>    <behaviors>      <serviceBehaviors>        <behavior name="CalculatorBehavior">          <serviceMetadata httpGetEnabled="true" />        </behavior>      </serviceBehaviors>    </behaviors>    <services>      <service behaviorConfiguration="CalculatorBehavior" name="Sevice.CalculatorService">        <endpoint address="" binding="wsHttpBinding" bindingConfiguration=""          contract="Contract.ICalculator" />
