Windows Phone map.setView() in portrait mode

I have a route displayed on a map in my Windows Phone. Now I want to fit the zoom based on the route which is drawn on the map.

I did the following:

this.map.SetView(LocationRectangle.CreateBoundingRectangle(locations));

locations is an array of GeoCoordinates. In landscape orientation it works perfectly, but when I switch to portrait orientation it doesn`t.

---EDIT---

Here is the relevant code:

In my draw method, which is called in my OnLoad-Method, my locations array gets filled here:

double[,] givenCoordinates;
private MapOverlay overlay;
private Microsoft.Phone.Maps.Controls.MapLayer layer = new Microsoft.Phone.Maps.Controls.MapLayer();
private List<GeoCoordinate> locations = new List<GeoCoordinate>();

private void drawMap()
{
    try
    {
        bool centerPosition = false;
        for (int i = 0; i < givenCoordinates.GetLength(0); i++)
        {
            GeoCoordinate tmpCoord;
            GeoCoordinate centerPoint = new GeoCoordinate(0, 0);

            Image image = new Image();
            BitmapImage myImage = new BitmapImage(new Uri(@"Images\pushpin.png", UriKind.Relative));
            image.Width = 40;
            image.Height = 40;
            image.Opacity = 10;
            image.Source = myImage;

            if (givenCoordinates[i, 0] != 0 && givenCoordinates[i, 1] != 0)
            {
                tmpCoord = new GeoCoordinate(givenCoordinates[i, 0], givenCoordinates[i, 1]);

                if (!centerPosition)
                {
                    centerPoint = new GeoCoordinate(givenCoordinates[i, 0], givenCoordinates[i, 1]);
                    centerPosition = true;
                }

                overlay = new MapOverlay
                {
                    GeoCoordinate = tmpCoord,
                    Content = image,
                    PositionOrigin = new System.Windows.Point(0.5, 1)
                };
                layer.Add(overlay);
                locations.Add(tmpCoord);
            }
        }
        delMap.Layers.Add(layer);

        Microsoft.Phone.Maps.Controls.MapPolyline line = new Microsoft.Phone.Maps.Controls.MapPolyline();

    }
    catch (Exception ex)
    {
        MessageBox.Show("Error loading the map!");
        MessageBox.Show(ex.Message);
    }
}

I call the setView() Method in my OrientationChanged event, in the Loaded event and after a button click, so you can easily restore zoom to default. Code:

private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
    this.delMap.SetView(LocationRectangle.CreateBoundingRectangle(locations));
}

private void btn_default_zoom_Click(object sender, RoutedEventArgs e)     
{
    this.delMap.SetView(LocationRectangle.CreateBoundingRectangle(locations));
}
private void PhoneApplicationPage_OrientationChanged_1(object sender, OrientationChangedEventArgs e)
{
     delMap.SetView(LocationRectangle.CreateBoundingRectangle(locations));
}

All of this works fine in landscape mode, none of them work in portrait mode, not even the button click.

I tried your code with this little change on when calling the drawMap

//just for testing a list of locations
givenCoordinates = new double[3, 2];
givenCoordinates[0, 0] = 23.4896;
givenCoordinates[0, 1] = 12.1392;
givenCoordinates[1, 0] = 23.4835;
givenCoordinates[1, 1] = 12.1794;
givenCoordinates[2, 0] = 23.5153;
givenCoordinates[2, 1] = 12.1516;



drawMap();

await Task.Run(async () =>
{
    Thread.Sleep(1);
    Dispatcher.BeginInvoke(() =>
    {
        delMap.SetView(LocationRectangle.CreateBoundingRectangle(locations), MapAnimationKind.Linear);
    });
});
