title: Is it possible to let my c# wpf program know if the user has a touchscreen or not?
body: <p>I've got an login application that has a swipe system that people only can use when they have a touchscreen. They can login by swiping their personal pattern swipe code.</p>
  
  <p>Is it possible to check in C# or WPF if the user has a touchscreen? Even when he isn't using touch on it at that time?</p>
