Developing Applications for Windows 8 Making Sense of the BUILD Announcements Joseph Cooney & Patrick Klug Live Backchannel: #dddbrisbane #mix01 @josephcooney @PatrickKlug

Slide 2

Windows 8 is touted by Microsoft as being a substantial step forward for the Windows operating system, as we move into a world of more diverse devices and form factors. At BUILD Microsoft revealed a number of details about client applications development for Windows 8 that they'd previously kept under wraps. With BUILD behind us we can all see the importance of WinRT and Metro UI, and the new direction for XAML. Come along to this session to get the back story on these changes, stay for the low-brow scatological analogies as we dive into the implications of all these announcements, before finally being driven away by vicious rumours and wild speculation about what Microsoft is keeping up their sleeve.

Slide 54

When appropriate, add a realistic, physical dimension to your application. Often, the more true to life your application looks and behaves, the easier it is for people to understand how it works and the more they enjoy using it. For example, people instantly know how to use the realistic address book that Contacts on iPad portrays.

Free listing service for legacy Apps on AppStore which just point to external website. Windows Phone & XNA News (none).
