I have the high end Retina Macbook Pro for a month now, this weekend I'm going to attend a WP7/8 app development workshop which I think most probably going to use Windows. And I don't have Windows in my machine yet obviously. Which method is the best for me to just simply use it for app developing? VMware Fusion 5? the old classic Bootcamp? or Parallel? I'm a first timer in term of app developing so I don't know which is the best for me.
