static void GetLocationCourseAndSpeed()
{
    GeoCoordinateWatcher watcher = new GeoCoordinateWatcher();

    watcher.TryStart(true, TimeSpan.FromMilliseconds(1000));

    if (!watcher.Position.Location.IsUnknown)
    {
        GeoCoordinate coord = watcher.Position.Location;

        Console.WriteLine("Course: {0}, Speed: {1}",
            coord.Course,
            coord.Speed);
    }
    else
    {
        Console.WriteLine("Unknown");
    }
}


Public Sub GetLocationCourseAndSpeed()
    Dim watcher As GeoCoordinateWatcher
    watcher = New System.Device.Location.GeoCoordinateWatcher()
    watcher.TryStart(False, TimeSpan.FromMilliseconds(1000))

    If Not watcher.Position.Location.IsUnknown Then
        Dim coord As GeoCoordinate = watcher.Position.Location
        Console.WriteLine("Course: {0}, Speed: {1}",
            coord.Course,
            coord.Speed) 'NaN if not available.
