Larry Osterman is a long time MS employee (he's been a developer at Microsoft for 29 years. 29 years!!!). He's also been a Niner since the beginning of Channel 9. So great to have him on C9 Live! Even better, of course, is the feature Larry has been working on in Windows 8.1: Automatic App Data Cache Updating! Tune in to learn about this excellent new feature for keeping Apps fresh even when they aren't running! Go Larry!! Martyn Lovell is also a long time MS engineer, with roots in the VC++ team and now managing the Windows Runtime engineering team. Excellent to have Martyn on C9 Live!! Tune in.
