我有 WCF (.net v4) 的通用托管服务。它允许以插件样式删除多个代理，每个代理都有自己的配置文件。它是作为服务编写的，因为所有站点都不会安装 IIS 或 WAS，但我们可以指定 .net v4 和我们的客户服务。

我们对 HTTP、HTTPS 或 TCP（没有凭据）没有任何问题。当我们向服务器添加证书时，它似乎可以毫无问题地启动。一旦我们尝试调用服务，我们就会得到一个通道故障。我们编写了一个小型自托管程序，该程序使用配置文件而不是以编程方式创建端点，它可以正常工作。我们只能推测我们错过了一个设置，但无法确定是哪个。

我们得到的错误如下所示。似乎由于某种原因，客户端尝试建立我们没有在主机中配置的双通道 tcp 连接。
