WCF-找不到端点异常

Question

两天来，我一直在为此绞尽脑汁，并尝试了许多方法试图让它发挥作用，但都无济于事。我正试图让这个系统在我的本地机器上运行，以进行调试。我希望这里有人能看到我视而不见的东西，或者能提供一些建议。

我有两个wcf服务（实际上是4个，但稍后会详细介绍）。一个是在IIS上运行的SOAP Web服务。Web服务正在尝试调用另一个服务（代理）。在生产环境中，两个服务之间有两个防火墙。他们使用具有证书安全性的net.tcp协议进行连接。

我们使用自签名证书进行开发和qa。

我已经安装了客户端和服务证书，并已授予应用程序池对证书的读取访问权限。

我已经验证了Net。Tcp端口共享服务，网络。Tcp侦听器适配器，网络。管道侦听器适配器都在运行。

net.tcp协议已启用，并且在IIS中定义了net.tcp绑定。

防火墙关闭。

这两个服务都连接到身份管理服务（IMS），该服务也是运行在qa服务器上的WCF服务，而不是我的本地计算机。Web服务能够成功连接到IMS服务。我正在尝试使用相同的绑定连接到代理服务。据我所知，web服务和代理之间的地址、绑定和契约都是匹配的，但我仍然得到EndPointNotFoundException。我错过了什么？

附录：我刚刚运行了netstat-a，在端口8102上没有看到任何侦听。很明显，这就是我得到回应的原因。我现在的问题是，为什么代理没有监听8102？我在Visual Studio 2015中运行了代理服务，并设置了断点。我需要安装服务然后连接到进程吗？

问题是这个应用程序的配置文件中有一个appSetting，它控制是否创建servicehost，并且该设置被设置为false。我不知道为什么配置文件中有这样的设置。然而，将appSetting设置为true只是揭示了一个全新的问题。那么，接下来的问题。
