我跟着從另一篇文章在計算器上點擊此鏈接：配置和使用WCFExtras - WCF/C＃/ VS2008
這是從我的WCF服務庫我的app.config。

我在這裏已經刪除了部分連接字符串部分。當我嘗試用[XmlComments]運行它給了我一個錯誤，例如：
Error: Cannot obtain Metadata from http://localhost:8731/TestClient.Service/Service1/mex
If this is a Windows (R) Communication Foundation service to which you have access,
please check that you have enabled metadata publishing at the specified address.
For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error
URI: http://localhost:8731/TestClient.Service/Service1/mex
Metadata contains a reference that cannot be resolved: 'http://localhost:8731/TestClient.Service/Service1/mex'.
