  <p>Here's the git page of the Material Design In XAML Toolkit (you can download the demo project here): <a href="https://github.com/ButchersBoy/MaterialDesignInXamlToolkit" rel="noreferrer">Toolkit:https://github.com/ButchersBoy/MaterialDesignInXamlToolkit</a></p>
  
  <p>This is probably property somewhere in the Material Design In XAML Toolkit library and i am asking if anyone knows how to set it (or if the overlay can even be turned off).</p>
