【问题标题】：Metadata contains a reference that cannot be resolved元数据包含无法解析的引用

【问题描述】：

我在 SO 上查看了一大堆其他帖子，但没有一个解决了我的问题。

我已经在本地机器上的 IIS 中设置了 WCF Web 服务，我可以正常浏览它，但是当我尝试将其添加为服务引用时出现此错误：

Metadata contains a reference that cannot be resolved: 'http://[Machine Name]/AccessSetupService/WebServices.Services.AccessSetupService.svc?wsdl'.
The WSDL document contains links that could not be resolved.
There was an error downloading 'http://[Machine Name]/AccessSetupService/WebServices.Services.AccessSetupService.svc?xsd=xsd0'.
The underlying connection was closed: An unexpected error occurred on a receive.
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
An existing connection was forcibly closed by the remote host
Metadata contains a reference that cannot be resolved: 'http://[Machine Name]/AccessSetupService/WebServices.Services.AccessSetupService.svc'.
Metadata contains a reference that cannot be resolved: 'http://[Machine Name]/AccessSetupService/WebServices.Services.AccessSetupService.svc'.
If the service is defined in the current solution, try building the solution and adding the service reference again.

具体来说，我不明白为什么它说它无法解析http://[Machine Name]/AccessSetupService/WebServices.Services.AccessSetupService.svc，而这是我正在浏览的确切地址。

这是我的配置文件：

<configuration>
  <system.web>
    <compilation debug="true"/>
  </system.web>
  <system.serviceModel>
    <services>
      <service name="WebServices.Services.AccessSetupService">
        <endpoint address="" binding="wsHttpBinding" contract="WebServices.Services.IAccessSetupV1">
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange">
        </endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://[Machine Name]/AccessSetupService/WebServices.Services.AccessSetupService.svc"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    <bindings>
      <wsHttpBinding>
        <binding name="wsHttpBinding"></binding>
      </wsHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="True"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

编辑：这是 WSDL：

有什么想法吗？我一直在用头撞墙上，我正在做的洞越来越大。

提前谢谢！

【问题讨论】：

您可以发布 WSDL 吗？ http://[Machine Name]/AccessSetupService/WebServices.Services.AccessSetupService.svc?wsdl

标签： wcf

【解决方案1】：

我授予 IIS_IUSRS 对 Windows/Temp 文件夹的读写权限，并且它起作用了

【讨论】：

谢谢！！我认为这很愚蠢……毕竟是 M$ :p

【解决方案2】：

我遇到了和这个类似的问题。特定机器上的 IIS 存在问题，将服务移动到另一台机器可能会暴露此问题。另外，请尝试让 Windows 重新安装 IIS，看看是否能解决问题。
