WCF 发现：EndpointNotFoundException，即使找到端点

我正在使用 WS Discovery 动态查找并连接到本地网络上的端点。

var cli = new DiscoveryClient (new UdpDiscoveryEndpoint ());
var response = cli.Find (new FindCriteria (typeof (IFoo)));

返回 net.tcp://localhost:8000/，这是正确的。但

var ep = new DynamicEndpoint (
    ContractDescription.GetContract (typeof (IFoo)), new NetTcpBinding ());
var cf = new ChannelFactory<IFoo> (ep);
var ch = cf.CreateChannel ();
ch.SomeMethod ();

抛出 EndpointNotFoundException 并显示以下消息：

“发现了 1 个端点，但客户端无法创建或打开与任何已发现端点的通道。”

我用谷歌搜索错误消息，但没有结果！发生了什么事，我该如何解决这个问题？

var ep = new DynamicEndpoint (

throws an EndpointNotFoundException with this message:
