windows 8: a tale of two stacks
DESCRIPTION
Microsoft has made a bold entry into the world of tablet PCs with the introduction of Windows 8. The new operating system poses an interesting challenge because it exposes a dual personality with desktop-based features (the “Blue stack”) and tablet-focused features in the Metro or “Green stack.” Jeremy Likness covers the new architecture for Windows 8 and highlights the differences between these stacks to help developers understand how to navigate their new options. In this webinar you will learn about the new WinRT component layer, legacy support, and the new options available for Windows 8 Metro-style development.TRANSCRIPT
