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

Question

我在 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/'.

System.ServiceModel

这些是在 Windows 中的某个地方，还是在我启动/停止进程时它们已注册和未注册？

为 Mex 使用不同的端点。它可能还需要与您的 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" />
