有没有办法使用NetNamedPipeBinding关闭双工模式（不支持IDuplexSessionChannel）

Question

我有一个简单的.NET（C＃）应用程序，有三个线程：主线程和两个主线程产生的线程。第一个子项用于初始化并启动 ServiceHost 实例，使用 IFirstService 合同进行操作。第二种是使用 ChannelFactory 创建与 FirstService 线程进行通信的渠道的客户端。 NetNamedPipeBinding 用于此渠道。

执行

启动应用程序后

$(value)[0].appendChild(newElement); 

预期输出应为

mono application.exe

但实际结果是

Using System.ServiceModel.NetNamedPipeBinding...
FirstService Host is opened
Hello from Second Thread
FirstService Host is closed

的Program.cs：

Using System.ServiceModel.NetNamedPipeBinding...
FirstService Host is opened
NamedPipeChannelListener.OnAcceptChannel
NamedPipeChannelListener.OnAcceptChannel.2
NamedPipeChannelListener.OnAcceptChannel.3
NamedPipeChannelListener.OnAcceptChannel

我可以避免使用DuplexSessionChannel吗？

Answer 1

我认为使用命名管道进行WCF（使用MMF作为其实现的一部分）不适用于Mono。

但是，您可以将NetTcpBinding与Mono一起使用。尝试将绑定更改为以下内容：

var binding_info = new BindingInfo
{
    binding = new NetTcpBinding(),
    uri = new Uri("net.tcp://localhost/ftest")
};
