2 客户端程序调用wcf，在配置文件中配置服务器的节点

1>新建“asp.net 空 web 应用程序”》在新建“wcf 服务”，直接将源码发布到iis中，

http://localhost/wcftest/MyFistService.svc?wsdl

2>在浏览器中打开以上地址，出现一下提示信息：

“若要测试此服务，需要创建一个客户端，并将其用于调用该服务。可以使用下列语法，从命令行中使用 svcutil.exe 工具来进行此操作“

svcutil.exe http://localhost/wcftest/MyFistService.svc?wsdl

3>安装2中的提示操作，在vs的命令窗口中执行以上操作，生成output.config和Service1.cs两个文件，将config中的配置节点服务到

自己的客户端程序中去，Service1.cs文件直接复制到客户端程序中。
