title: please explain what is themes and generic.xaml?
body: <p>i noticed that when i create a custom control in visual studio it adds generic.xaml into the Themes folder.</p>
  
  <p>what is the purpose of this folder, what is special about generic.xaml? why when i try to link to my own dictionaries from generic.xaml they do not seem to get picked up by the application?</p>
  
  <p>thanks!
