在Windows 2008上的Windows服务中托管WCF（mex端点）服务

Question

我正在Windows托管服务中托管WCF服务。

当我启动WHS时，我收到以下错误：

---

The ChannelDispatcher at 'net.tcp://mysecreturl/' with contract(s) '"IClass"' is unable to open its IChannelListener.

System.InvalidOperationException: A registration already exists for URI 'net.tcp://mysecreturl/Indexer/'.
   at System.ServiceModel.Channels.UriPrefixTable`1.RegisterUri(Uri uri, HostNameComparisonMode hostNameComparisonMode, TItem item)

System.ServiceModel

这些是在Windows中的某个位置，还是在我启动/停止进程时注册和取消注册？

为Mex使用不同的端点。它可能需要与net.tcp端口不同的端口号。如果你的net.tcp端口是8000，那么试试

<endpoint address="net.tcp://mysecreturl:8001/Mex" 
          contract="IMetadataExchange" />
