I'm a geekette who enjoys playing with new technology for software developers. I work as a Developer Evangelist for Microsoft. My current focus is on Windows Store development for Windows 8.
I’ve talked to many developers who are excited about Metro app development, but say that the hardest part is coming up with an app idea. Some folks want to walk through converting an existing app to Metro as a learning exercise. There are other folks who have very successful websites or apps that they would like to make available on Windows 8 too.
There are a lot of useful resources out there on porting existing applications to Metro apps that will run beautifully on Windows 8:
Porting a website
Porting existing XAML apps (WPF, Silverlight, and Windows Phone apps)
Leave a comment if you find other useful resources on transitioning to Metro.
