Arturo Toledo is the Chief Architect at Toledo Design (www.toledo2.com). In this video, Arturo talks about the Microsoft design principles as they apply to Windows and Windows Phone apps. He tells us what he learned as a designer in the Microsoft design studios, what he's learned from his independent consulting work, and how seeing the distinction between design principles and design language can open up new possibilities to you. Arturo has created an enormous resource called 24 Weeks of Windows Phone Design (http://www.toledo2.com/2012/10/23/24-weeks-of-windows-phone-design/ ), and the Microsoft design principles themselves are described here: https://msdn.microsoft.com/library/windows/apps/hh781237.aspx.
