Windows Store Simulator Portrait resolution issue


I have a small code which I am running on the Simulator in the Portrait mode, for example by rotating a 1280 x 800 device. For some unknown reason the screen size remains the same, instead of having the sizes changing between height and width. If I am drawing, as seen below, a rectangle of 700x700, the resulting rectangle on the simulator will show that the height is considered as having 800 pixels and width having 1280 pixels, even the simulator is in portrait mode.

    public class Game2 : Game
    GraphicsDeviceManager graphics;
    SpriteBatch spriteBatch;
    Texture2D pixel;

    public Game2()
        graphics = new GraphicsDeviceManager(this);
        IsMouseVisible = true;
        Content.RootDirectory = "Content";

    protected override void LoadContent()
        pixel = new Texture2D(GraphicsDevice, 1, 1, false, SurfaceFormat.Color);
        pixel.SetData(new[] { Color.White });
        spriteBatch = new SpriteBatch(GraphicsDevice);

    protected override void Draw(GameTime gameTime)

        spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend);
        spriteBatch.Draw(pixel, new Rectangle(0, 0, 700, 700), Color.Red);


Is there a special configuration or workaround for this situation, or is a simulator issue?

Thank you.
