IIS上包含元数据的WCF服务错误

我正在尝试将服务发布到IIS，它在ASP.NET开发服务器上构建并运行正常。在IIS中运行时，我可以通过导航到服务或在Visual Studio中添加服务引用来访问元数据。但是，当我从客户端应用程序调用一个方法时，它会因内部服务器错误而崩溃。因此，我查看了事件日志并发现：

WebHost failed to process a request.
 Sender Information: System.ServiceModel.Activation.HostedHttpRequestAsyncResult/8810861
 Exception: System.Web.HttpException (0x80004005): There was no channel actively listening at 'http://mysite.net/soundhubservice.svc/$metadata'. This is often caused by an incorrect address URI. Ensure that the address to which the message is sent matches an address on which a service is listening. ---> System.ServiceModel.EndpointNotFoundException: There was no channel actively listening at 'http://mysite.net/soundhubservice.svc/$metadata'. This is often caused by an incorrect address URI. Ensure that the address to which the message is sent matches an address on which a service is listening.

我的Web.Config如下所示：

<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <services>
      <service name="SoundHub.Services.SoundHubService" behaviorConfiguration="StreamingServiceBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost/SoundHubServive"/>
          </baseAddresses>
        </host>
        <endpoint address="service" binding="basicHttpBinding" bindingConfiguration="httpBuffering" contract="SoundHub.Services.ISoundHubService"/>
        <endpoint address="stream" binding="basicHttpBinding" bindingConfiguration="HttpStreaming" contract="SoundHub.Services.ISoundHubStreamService"/>
        <!--<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />-->
      </service>
    </services>

    <bindings>
      <basicHttpBinding>
        <binding name="HttpStreaming" maxReceivedMessageSize="67108864" transferMode="Streamed"/>
        <binding name="httpBuffering" transferMode="Buffered" />
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="StreamingServiceBehavior">
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>

  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

我在网上搜索时尝试了几种设置组合，但没有任何帮助，总是相同的错误

谢谢

当我返回的一个对象包含枚举时，我遇到了这个问题；结果是它不知道如何序列化它

如果这是您的问题，请尝试返回枚举的int值（或字符串值），并将其强制转换回客户端的枚举。

获得相同的错误
