在 Windows 2008 上的 Windows 服务中托管 WCF(mex 端点)服务 [英] Hosting a WCF(mex endpoint) service inside a windows service on windows 2008

问题描述

我在 Windows 托管服务中托管 WCF 服务.

I'm hosting a WCF service inside a windows hosted service.

当我启动 WHS 时，出现以下错误:

When I start the WHS, I get the following error:

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/停止进程时注册和取消注册?

Are these somewhere in Windows or are they registered and unregistered when I start/stop the process?

推荐答案

为 Mex 使用不同的端点.它可能也需要与您的 net.tcp 端口不同的端口号.如果你的 net.tcp 端口是 8000 然后试试

Use a diffeent endpoint for Mex. It probably needs a different port number from you net.tcp port as well. If your net.tcp port is 8000 then try

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