Carl and Richard talk to Greg Levenhagen about Windows 8 development. Greg digs into the concept of contracts in Windows 8 and how they different from an API call, providing better control over how Win 8 applications work with services and resources of the OS. There's the obligatory debate over what Windows 8 Apps formally known as 'Metro' are now called... Windows 8 Store Apps? Modern Apps? Sigh. Greg also talks about how developers can get a handle on the user interaction side of Windows 8 Apps, life without a designer and his experiences interacting with the Windows 8 Store folks.
