c# - 无法让 WCF Duplex ChannelFactory 正确出错

Question

给定一个有效的 Binding 和 EndpointAddress，我有一个 WCF Duplex ChannelFactory，如下所示：

NetTcpBinding svcBinding = new NetTcpBinding();
svcBinding.ReliableSession.Enabled = true;
EndpointAddress svcEndpointAddress = new EndpointAddress(new Uri("net.tcp:// + ServiceAddress + "/Service"), EndpointIdentity.CreateDnsIdentity(UserPrincipalName));

DuplexChannelFactory dcf = new DuplexChannelFactory<IService>(new InstanceContext(this), svcBinding);
dcf.Opened += OnCommunicationOpened;
dcf.Faulted += OnCommuicationFaulted;
IService svc = dcf.CreateChannel(svcEndpointAddress);

public void OnCommunicationOpened(object sender, EventArgs e)
{
    // do something . . .
}

public void OnCommunicationFaulted(object sender, EventArgs e)
{
    // do something else . . .
}

打开的事件触发没有问题，但是当我关闭我的服务时，错误的事件没有触发。如何让 Faulted 事件触发？
