title: WinRT and WPF in Windows 8
body: <p>As I understand, WinRT is a different version of WPF written without using the underlying Win32 APIs.</p>
  
  <p>What's the relation of WinRT and WPF? Will WPF work under Metro in Windows 7 or will it launch the classic desktop?</p>
  
  <p>That's not so clear from the Keynote. If someone has Windows 8 installed can confirm it's behaviour.</p>
  
  <p>Thanks</p>
