title: Content Resized event for WPF app
body: <p>For some scaling recalculation in a Silverlight application I use the following event: </p>
  
  <pre><code> App.Current.Host.Content.Resized += new EventHandler(Content_Resized);
  </code></pre>
  
  <p>I'd like to use a similar event in a WPF application, but can not figure out what it should be.</p>
  
  <p><strong>What is an equivalent of Silverlight's <code>App.Current.Host.Content.Resized</code> for a WPF application?</strong></p>
