3. Windows 7 As of //build 2011  450,000,000 copies of Windows 7 sold  Internet Explorer 9 is the fastest growing Windows 7 browser  542,000,000, people signing into Windows Live services

4. Changing world of computing As of //build 2011  Form factors and user interactions models create new scenarios and opportunities  Mobility means devices you use while carrying, not just devices you carry  App developers want rich connectivity and sharing capabilities, connection to customers  Services are intrinsic in all software

5. Windows 8  Makes Windows 7 even better Everything that runs on Windows 7 still runs on Windows 8  Reimagines Windows from chipset to experience New range of capabilities, scenarios and form factors

23. The Windows Store (More Later Today)  Designed for discovery  Unprecedented reach  Flexible business models  Best economics

24. App Execution Environment

25. Metro Style App Acquisition Windows Store backend Package Manager Windows Store install Execution Engine Extension Handler stage Single instance store register Registration Information

26. Building Blocks of an App Package  App Manifest contains all information needed to deploy the app  Blockmap contains hashes of all files within the app package  Signature validates the integrity of the app package AppXManifest.xml BlockMap Signature Zip Central Directory Files / Assets.appx package

27. App Manifest and Capabilities  Explicitly declares the app integration endpoints  File capabilities (music/pictures/videos/documents libraries, removable storage)  Devices (webcam, microphone, location, sms, proximity); extensible to new device classes  Network and identity (internet, private network, credentials)  File type associations  App contracts (search, share, etc.)  Contained in appxmanifest.xml; Visual Studio provides editor
