O'Neil is structuring this around the Generation App program, which takes new developers through a thirty day course that ends with marketplace submission and publication.
Generation App. It’s a free program that provides a structured, self-paced flow of information over a span of thirty days to lead you from installing the tools all the way through submitting your app to the marketplace. I’m currently on Day 3 and have a killer mini-browser to impress my friends and family.
If you're looking for a diversion over the festive holidays, perhaps getting started with WP8 development is for you? You can follow Jim at his blog, and if you do end up with a great application, let us know here at AAWP when you publish it!
