1. Platform for building Windows Store Apps Agu Suur Frontend Developer Axinom

2. Agenda Introduction to the Windows 8 Platform Introduction to the APIs, StoreLet’s build something! You’ll leave understanding: The Windows 8 Platform investments

3. Windows reimagined A new UI where touch is a first-class citizen along with full mouse-and-keyboard support New development models built on WinRT, including native support for HTML/CSS/JS, C#/XAML, C++/DirectX Designed from the chipset up for multiple form- factors – tablets, laptops, desktops & all-in-ones The Windows Store on every device with a full commerce platform and flexibility

5. Windows 8 Experience  Fast and fluid user experience Responsive, alive, beautiful  Immersive and full-screen Focuses attention on your apps  Touch-first with full keyboard and mouse Enables your choice of interaction  Web of apps working together Apps are connected to each other and the cloud  Experience for all PC devices and architectures  No compromise across new form factors, desktops and laptops

11. What did we see…  WinRT APIs are asychronous  WinRT APIs provide rich access to device, OS and services  WinRT APIs feel natural in C#, Javascript and C++

12. App Execution Environment

13. Windows Store app acquisition Windows Store backend Package Manager Windows Store install Execution Engine Extension Handler stage Single instance store register Registration Information

14. 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

15. 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
