这是我的 WCF 配置，但是当我尝试添加服务引用时

net.tcp://127.0.0.1:8731/IMSSDirectoryService

我收到一个错误：

元数据包含无法解析的引用：'net.tcp://localhost:8731/IMSSDirectoryService'。

如果在当前解决方案中定义了服务，请尝试构建解决方案并再次添加服务引用。请帮助我理解我的问题。

Answer 1

您定义了两个相同的基地址：

<service name="SUR.Core.Service.Implementation.SURDirectoryService" 
         behaviorConfiguration="DefaultServiceBehavior">
  <host>
    <baseAddresses>
      <add baseAddress="net.tcp://127.0.0.1:8731/ISURDirectoryService"/>
    </baseAddresses>


<service name="MSS.Core.Service.Implementation.MSSDirectoryService" 
         behaviorConfiguration="DefaultServiceBehavior">
   <host>
     <baseAddresses>
       <add baseAddress="net.tcp://127.0.0.1:8731/IMSSDirectoryService"   />

这就是您的问题的原因 - 当连接到 net.tcp://127.0.0.1:8731/ 时，WCF 不知道您指的是哪个服务。

基地址在其“架构”中必须是唯一的（例如 http、net.tcp 等）

编辑：如果您希望能够使用浏览器检索元数据并导航到 URL 以获取它，则需要在服务行为选项中激活 <serviceMetadata httpGetEnabled="True"/>。否则，您将只能通过 net.tcp 使用 SOAP 调用来获取元数据 - 例如使用 Visual Studio 9/Common7/IDE 文件夹中的“WcfTestClient.exe”应用程序。

编辑 2：您已经为 MEX 定义了许多额外的绑定和行为，但是由于您的任何 mex 端点实际上都没有引用任何这些设置，因此它们没有被使用。

Answer 2

我解决了这个问题，我只是将 MSS 服务的 mex 绑定更改为 http。非常感谢 marc_s 你的回复帮助我理解了这个问题！
