I've had the opportunity to publish a two part article on Smashing Magazine, covering Windows 8 app development using HTML5, the Microsoft cloud offering Azure Websites and Composite C1.

The article contain full source code and all the guidance needed to get a fully featured and customized online magazine app running on Windows 8.
