Hi Nrk_hi,

You could start from the following article.

Asynchronous Operations in WCF

http://social.technet.microsoft.com/wiki/contents/articles/16346.asynchronous-operations-in-wcf.aspx 

[ServiceContract]
public interface IService1
{
    //event-based asynchronous pattern
    [OperationContract]
    string GetData(string message);
}

public class Service1 : IService1
{
    public string GetData(string message)
    {
        Thread.Sleep(5000);
        return message;
    }
}

class Program
{
   static wsService1.Service1Client client1 = new wsService1.Service1Client();
 
   static void Main(string[] args)
   {
       client1.GetDataCompleted += client_GetDataCompleted;
       client1.GetDataAsync("event-based asynchronous pattern");
       Console.WriteLine("Waiting for async operation...");
       Console.ReadLine();
   }
 
   static void client_GetDataCompleted(object sender, wsService1.GetDataCompletedEventArgs e)
   {
       Console.WriteLine(e.Result.ToString());
   }
}

Best Regards,

Chris

You can't directly add service reference programmatically. 

The WCF client proxy can be generated within Visual Studio using the Add Service Reference feature. If you want to create proxy class without adding service reference, you could use ChannelFactory class to generate service proxy.
