How to call web service programmatically from Silverlight?

I'am trying to access WebService from Silverlight and call some its method.

I tried to use example from: http://www.codeproject.com/Tips/394436/Calling-a-webservice-programmatically

// In Silverlight it is not posible to use this 
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

But it is not applicable for Silverlight application. Do you have any example how to connect to WebService from Silverlight and then call its method?

Silverlight doesn't allow you to perform IO task synchronously to keep your application responsive. That's why GetResponse() ist not available. You need to get the response asynchronously:

WebRequest request = WebRequest.Create(/* URI */);
request.BeginGetResponse(HandleResponse, request);

The delegate you pass to the method will be invoked when the repsonse is available. Example implementation of this method:

private void HandleResponse(IAsyncResult result)
{
  WebRequest request = (WebRequest)(result.AsyncState);

  using (var response = request.EndGetResponse(result))
  {
    // do something with the response
  }
}
