添加WCF服务引用时,不会将配置详细信息添加到web.config

我正在尝试使用VS2010向我的Web应用程序添加WCF服务引用.它似乎添加OK,但web.config没有更新,这意味着我得到一个运行时异常： @H_874_2@显然,因为我的web.config中没有定义服务.重现步骤：

@H_874_2@>右键单击解决方案>添加>新项目> ASP.NET空Web应用程序.
>右键单击新Web应用程序中的服务引用>添加服务参考.
>输入我的服务地址,然后单击“执行”.我的服务在左侧的“服务”部分中可见,我可以看到它的所有操作.
>为我的服务键入命名空间.
>单击“确定”.正确生成服务引用,我可以打开Reference.cs文件,看起来一切正常.
>打开web.config文件.它还是空的！

<system.web>
    <compilation debug="true" targetFramework="4.0" />
</system.web>


<system.serviceModel>
    <bindings />
    <client />
</system.serviceModel>

@H_874_2@为什么会这样？它也适用于控制台应用程序或我尝试的任何其他项目类型.有帮助吗？

@H_874_2@这是我的WCF服务的app.config：

<?xml version="1.0"?>

  <system.web>
    <compilation debug="true" />

  <!-- When deploying the service library project,the content of the config file must be added to the host's 
  app.config file. System.Configuration does not support config files for libraries. -->
