我有一个WCF p2p网状网络,可以正常运行单向对话。我正在调查是否可以调用一个方法来添加两个数字并返回和总和。
但是在尝试连接时遇到错误:
合同需要请求/回复,但是绑定'NetPeerTcpBinding'不支持它,或者没有正确配置以支持它。
C#Connect
private void button1_Click(object sender, EventArgs e)

// An instance of ChatApp is created and passed to the InstanceContext.
InstanceContext instanceContext = new InstanceContext(new ChatApp(radTextBoxusername.Text, this));
// Create the participant with the given endpoint configuration
// Each participant opens a duplex channel to the mesh
// participant is an instance of the chat application that has opened a channel to the mesh
factory = new DuplexChannelFactory<IChatChannel>(instanceContext, "ChatEndpoint");
participant = factory.CreateChannel();
// Retrieve the PeerNode associated with the participant and register for online/offline events

IOnlineStatus ostat = participant.GetProperty<IOnlineStatus>();
ostat.Online += new EventHandler(OnOnline);
ostat.Offline += new EventHandler(OnOffline);
try

participant.Open();
