无法从另一个wcf服务iis 7中找到wcf服务

在实例化不同服务的行上，我从IIS 7得到一个编译错误

CS0246:找不到类型或命名空间名称“MyOtherService”。是否缺少using指令或程序集引用

是否需要在web.config文件中为该服务添加另一个程序集引用？这是我的网页配置：

请检查以下元素：

<service name="MyService">
     <endpoint binding="wsHttpBinding" behaviorConfiguration="webHttp" contract="MyService">
       <identity>
         <dns value="https://IPADDRESS:443"/>
       </identity>
     </endpoint>
     <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
 </service> 

服务元素中的name属性应该是完全限定的。例如：namespace.MyService是需要显示的值

对于端点元素中的contract属性也是一样的，它应该是完全限定的。

例：namespace.IMyService

这与此无关。我拥有所有这些。我甚至使用服务的完全限定名称。我的项目中有网络参考。我在Oracle.DataAccess中遇到了同样的错误，通过在//
