title: How do I deploy to a Windows Phone 7 device?
body: <p>I've been coding something in XNA 4.0 and running things through an emulator. I tried deploying to an actual Windows Phone 7 device but the compiler said there were deployment errors. It says htis exactly: 'There were deployment errors. Continue?' and if I hit 'yes' I get another messagebox which says 'unable to start debugging'.</p>
  
  <p>I've looked online and can't find any resources on this weird problem I'm having. I've plugged in the phone via USB but that's all I can think of doing, am I missing something else?</p>
