Live from San Francisco, Microsoft Premier Field Engineers Robert Evans and Christophe Nasarre present demos and code for some of the exciting new features of these technologies from a unique developer perspective. You’ll see the impact of the new tiles size in your manifest and their support for live tiles. Next, you’ll discover how to integrate the new DatePicker, TimePicker, CommandBar, SettingsFlyout in your code. Don’t miss the XAML to bitmap rendering demo!

In addition, the different steps to retarget your App for Windows 8.1 are detailed with great tricks to support the new resize behaviour compared to the Windows 8 snapped mode.

Last but not least, you will be able to dig into the list of new WinRT API thanks to the WinmdDiff tool.
