title: Get window width / height in Windows store apps
body: <p>I currently have a basic page which loads, and I need some way of obtaining the width and height of the window, preferably in the constructor. The problem is, in the constructor, or before the page is completely loaded, I can't seem to get hold of the width and height. After it is loaded I can just use:</p>
  
  <pre><code>this.ActualWidth;
  this.ActualHeight;
  </code></pre>
  
  <p>Is there any window load complete event I can use or any way to obtain the width and height during the loading?</p>
