注意：

引用程序集System.ServiceModel.dll

帮助：项目的配置文件右键-编辑WCF配置，此工具可以方便的配置wcf配置

一.定义服务契约：（本质就是接口加ServiceContract特性）

 [ServiceContract]
    public interface IBookService
    {
        [OperationContract]
        string GetBook(int num);
    }

二.实现契约：（实现接口）

 public class BookService : IBookService
    {
        public string GetBook(int num)
        {
            return $"第{num}章内容";
        }
    }

三.服务配置：

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="UserBinding" />
        <binding name="BookBinding" />
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="UserBehavior">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="false" />
        </behavior>
        <behavior name="BookBehavior">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="UserBehavior" name="LFN.TCAL.WCFService.UserService">
        <endpoint address="UserService" binding="basicHttpBinding" bindingConfiguration="UserBinding"
          name="UserEndpoint" contract="LFN.TCAL.WCFService.IUserService" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:55958/" />
          </baseAddresses>
        </host>
      </service>
      <service behaviorConfiguration="BookBehavior" name="LFN.TCAL.WCFService.BookService">
        <endpoint address="BookService" binding="basicHttpBinding" bindingConfiguration="BookBinding"
          name="BookEndpoint" contract="LFN.TCAL.WCFService.IBookService" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:55958/" />
          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>

四.实现契约：

客户端项目新建BookServiceClient 类并继承ClientBase类，实现契约接口IBookService

  public class BookServiceClient : ClientBase<IBookService>, IBookService
    {
        public string GetBook(int num)
        {
            return base.Channel.GetBook(num);
        }
    }

五.客户端配置：

  <system.serviceModel>
        <behaviors />
        <bindings>
            <basicHttpBinding>
                <binding name="BookBinding" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost:8001/BookService.svc/BookService"
                binding="basicHttpBinding" bindingConfiguration="BookBinding"
                contract="LFN.TCAL.WCFService.IBookService" name="BookEndpoint"
                kind="" endpointConfiguration="" />
        </client>
    </system.serviceModel>

六.客户端调用WCF服务：

  class Program
    {
        static void Main(string[] args)
        {
            using (BookServiceClient client = new BookServiceClient())
            {
                var str = client.GetBook(3);
                Console.WriteLine(str);
                Console.Read();
            }
        }
    }

结果输出：第3章内容
