title: WinRt: Dispose a page
body: <p>I'm wondering how to dispose a Page correctly in WinRT.</p>
  
  <p>In my page_loaded event I hook several events like:</p>
  
  <pre><code>_navigationHelper.LoadState += navigationHelper_LoadState;
  _navigationHelper.SaveState += navigationHelper_SaveState;
  _button.Click += button_click;
  </code></pre>
  
  <p>As I don't have an instance from my page I can not dispose it.
  Am I responsible to unhook such events?</p>
  
  <p>Is it right that if the destructor is called everything is disposed and the GC takes care of all references?</p>
  
  <p>Many thanks
  Dani</p>
