copied!<p>Following is an example of running host and client where host can log message on the console. On your example, I am not sure why you have set <code>IsOneWay=true</code>. For this specific case, one way is not what you want. Also, I have used net.tcp binding in the following example; it should work with any other binding as well.</p> <p>Basically in the example, user's entry is sent to the host service which echos the message on the console.</p> <pre><code>[ServiceContract] public interface IProdsService { [OperationContract] void Alert(string msg); } /// <summary> /// Host Class /// </summary> public class ProdsService : IProdsService { public ProdsService() { Console.WriteLine("Service instantiated."); } public void Alert(string msg) { Console.WriteLine(msg); } } /// <summary> /// Client proxy wrapper /// </summary> public class ProdsServiceClient : ClientBase<IProdsService>, IProdsService { public ProdsServiceClient() { } public ProdsServiceClient(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress) : base(binding, remoteAddress) { } public void Alert(string msg) { base.Channel.Alert(msg); } } class Program { static ManualResetEvent _reset; static void Main(string[] args) { string host = "localhost"; int port = 8888; //ManualResetEvent is used for syncing start/stop of service. _reset = new ManualResetEvent(false); var action = new Action<string, int>(Start); var result = action.BeginInvoke(host, port, null, null); //Wait for svc startup, this can be synced with resetEvents. Thread.Sleep(2000); //Create a client instance and send your messages to host using (var client = new ProdsServiceClient(new NetTcpBinding(), new EndpointAddress(string.Format("net.tcp://{0}:{1}", host, port)))) { client.Alert("Test message"); string msg = string.Empty; do { Console.Write("Type a message to send (X to exit): "); msg = Console.ReadLine(); client.Alert(msg); } while (!msg.Trim().ToUpper().Equals("X")); } //Signal host to stop _reset.Set(); action.EndInvoke(result); Console.Write("Press any to exit."); Console.ReadKey(); } static void Start(string host, int port) { string uri = string.Format("net.tcp://{0}:{1}", host, port); //var server = new ProdsService(); ServiceHost prodService = new ServiceHost(typeof(ProdsService)); prodService.AddServiceEndpoint(typeof(IProdsService), new NetTcpBinding(), uri); Console.WriteLine("Service host opened"); prodService.Open(); //Wait until signaled to stop _reset.WaitOne(); Console.WriteLine("Stopping host, please wait..."); prodService.Close(); Console.WriteLine("Service host closed"); } } </code></pre>
