Finally, I managed to put the time to complete the updated version of the Window Phone 8.0 Developer Roadmap and compile the Windows Phone 8.1 version of it.
For those of you who are new to such developer roadmaps, it’s simply a compilation of lots of Windows Phone 8.1 developer resources represented in hyperlinks with some checkpoints that should help you getting started with the platform (Learning, Porting, Designing, Building, Testing, Publishing, and Monetizing your app)
You can download the roadmap from here.
Kindly share with your developers and community.
Make sure you click through as the PDF is fully hyperlinked, etc....
