Accessing the Västtrafik API from Windows Phone 7

[NOTE: The Västtrafik API has changed so this post is obsolete.]

I have been working on a Windows Phone 7 app that would make my commuting to work a bit easier (Västtrafik is not the most reliable commuting service ).

Västtrafik publishes a very neat web service API that is free to use if your are registered in their community (http://labs.vasttrafik.se) and here is some code snippets on how to use it:

public class Class1
{
    private const string VASTTRAFIK_ID = "...";

    private const string STOP_ID = "00012711!-1186562910";

    protected Class1()
    {
        this.wcfClient = new VasttrafikNextTripService.NextTripSoapClient();
        this.wcfClient.GetForecast1Completed += wcfClient_GetForecast1Completed;
    }

    public override void UpdateAsync()
    {
        this.wcfClient.GetForecast1Async(VASTTRAFIK_ID, STOP_ID);
    }

    protected override void EndUpdate()
    {
        this.wcfClient.Abort();
    }

    private void wcfClient_GetForecast1Completed(object sender, VasttrafikNextTripService.GetForecast1CompletedEventArgs e)
    {
        if (e.Error == null)
        {
            var result = ParseXml(e.Result);
        }
        else
        {
            this.latestVasttrafikTripInfo = null;
        }
        this.OnTripInfoUpdated();
    }
}
