This year at TechEd on the Gold Coast I delivered two sessions:
DEV324: Windows 8 with a view
A session where I took MVVM as a base to launch your applications to the next level.
WPH222: Windows Phone SDK – Be productive straight out of the blocks
Think of this one as you’ve started your first serious application, what are some of the common issues you’ll run in to, and what are the common techniques you’ll need.
