在Windows 2008的Windows服務中託管WCF（mex endpoint）服務

Question

我在Windows託管服務中託管WCF服務。

當我開始WHS的，我得到以下錯誤：

---

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/'.

System.ServiceModel 

難道這些地方在Windows或者是他們註冊與未註冊的時候我開始/停止的過程？

爲Mex使用diffeent端點。它可能需要一個與你的net.tcp端口不同的端口號。如果您的net.tcp端口是8000，那麼請嘗試

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