Question

I have implemented a simple chat console app and it worked well. When i tried to apply the same concept on GUI app. the service side when hosting , there is any error but if i use CMD command netstat -ao to show all ports , it is not exists.So when i run client app , there is an Exception (No connection could be made because the target machine actively refused). How can i solve these problem ?

Server

ServiceHost host;
using (host = new ServiceHost(typeof(Service), new Uri("net.tcp://localhost:4111")))
{
    host.AddServiceEndpoint(typeof(IService), new NetTcpBinding(), "IService");

    try
    {
        host.Open();

    }
    catch
    {
    }
}

Client

public bool Connect()
{
    DuplexChannelFactory<IService> pipeFactory = new DuplexChannelFactory<IService>(new InstanceContext(this),
                                                                                    new NetTcpBinding(),
                                                                                    new EndpointAddress(AppConfiguration.GetValue(net.tcp://localhost:4111/IService"));

    try
    {
        pipeProxy = pipeFactory.CreateChannel();
        if (pipeProxy.Register())
        {
            return true;
        }
    }
    catch
    {
    }
    return false;
}

I have solve it.
In GUI remove the (using) at defined new ServiceHost. Why i don’t know but it works!!!

ServiceHost host;
host = new ServiceHost(typeof(Service), new Uri("net.tcp://localhost:4111"));
