Implementierung asynchroner Web Service

[afroDeluXe]

Hi ihr..
ich habe Probleme einen asynchronen Web Service mit C# und .Net Framework 4.5 zu realisieren. Leider habe ich bisher noch keine Lösungen gefunden, wie ich die Methodenaufrufe und Funktionen async-gerecht implementieren kann. Vielleicht hat einer von euch schon Erfahrung damit..

var binding = new BasicHttpBinding();
binding.MaxReceivedMessageSize = int.MaxValue;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
var address = new EndpointAddress("http://server:port/Webservice");

WebserviceClient client = new WebserviceClient(binding, address);
client.ClientCredentials.UserName.UserName = "UNAME";
client.ClientCredentials.UserName.Password = "PWORD";

WebserviceRequest request = new WebserviceRequest();
request.Nummer = inputNumme.Text;                                     //aus TextBox

WebserviceResponse response = await client.WebserviceAsync(request);

InfoKlasse Rueckmeldung = response.Return[0];
var _message = Rueckmeldung.Message;

showListBlock.Text = _message;                                          //in Ausgabe-TextBox

Vielen Dank für eure Mühen..

Beispiel: (while(true) damit die Methode nicht verlassen wird.)
Es werde Int32-Werte über einen Zeitraum geliefert, bzw. angefragt.

   
[STAThread]
static void Main(string[] args)
{ 
             using (WebReference1.Service1 svr = new WebReference1.Service1())
            {
                svr.MyWebServiceMethodCompleted += new MyWebServiceMethodCompletedEventHandler(svr_MyWebServiceMethodCompleted);
                svr.MyWebServiceMethodAsync(DateTime.Now.AddDays(-10), DateTime.Now);
            }

            while (true)
                System.Threading.Thread.Sleep(10);
}


        static void svr_MyWebServiceMethodCompleted(object sender, MyWebServiceMethodCompletedEventArgs e)
        {
            throw new NotImplementedException();
        }

hm.. danke für deine Hilfe..... aber ehrlich gesagt kann ich damit nicht allzu viel anfangen :/ Hilft dir vllt DAS weiter bei meiner Problemstellung!?
Danke nochmals..

Der generierte Async-Aufruf:

        public System.Threading.Tasks.Task<WS_weather.ZAL_ENTRYSHEET_DELETE.EntrysheetDeleteResponse> EntrysheetDeleteAsync(WS_weather.ZAL_ENTRYSHEET_DELETE.EntrysheetDeleteRequest request) {
            return base.Channel.EntrysheetDeleteAsync(request);
