11. Windows 8.1 provides developers with a shared platform that renders the right app experience for the right form-factor
Designed once; engaging everywhere
• Converged developer platform
• Converged app model
• Shared app identities + entitlement
• Unified push services (via WNS)
Apps come to life on Windows
• Live tile improvements
• Action Center for smart notifications
• Background execution + triggers
• Bluetooth-LE support for wearables + beacons
• Internet Explorer 11 improvements
12. Windows Phone 7.5 Windows Phone 8.0 Windows Phone 8.1
Convergence Begins with IE
• WP 7.5 shipped with IE9
• Same IE codebase as
Windows
• Same JavaScript engine as
Windows
Converged Core OS
• Common NT kernel, file
system and core
networking
• Kernel mode driver f/work
• Secure boot & BitLocker
Developer Platform
• Partial API convergence
(focus on sensors & IAP)
• Native Code (C++) and
DirectX
• IE10
Converged Dev Platform
• More skillset reuse
• More code reuse
• More seamless app
experiences
Aligning the Stores
• Shared dev registration
• Shared entitlement
Common Core Platform
• Proximity & Location
frameworks
• Security & identity
• Task scheduler
13. The Windows Runtime (WinRT) is the shared
runtime and API space used by store apps
across the Windows platform (phone and
client)
Dramatic convergence in 8.1
• Goal is 100% convergence for dev scenarios
• In 8.0, we had ~30% API convergence
• With 8.1, we move well past 90%+ convergence
23. Windows Notification Service
(WNS)
• Shared push service for Windows +
Phone
• Improved queuing to limit lost
notifications due to intermittent
network connectivity
Tile templates + toasts
• Shared tile templates (more!)
• Periodic tile updates
• Toasts
24. Central location to surface
missed notifications
Apps can intelligently manage
notifications
(silently add, update, and delete
notifications)

• Adaptive streaming
• Secure viewing
• Accessibility improvements
WebGL support
Web spec based on OpenGL ES 2.0, to enable use of low-level
3D graphics APIs on web sites and HTML-based apps

42. Approach Pros & Cons
Keep using Silverlight 7.x/8
(Windows Phone 8 platform)
Pros
Will run on Windows Phone 8.1 (app compatibility),
still runs on earlier Windows Phone devices
Cons
Will not take advantage of new platform capabilities
Will not enable targeting of Windows
Use Silverlight 8.1
(Move Silverlight app into new execution
stack and app package)
Pros
Enables existing Silverlight apps to take advantage of
nearly all new APIs and platform capabilities
Cons
Will not enable targeting of Windows
Will not run on Windows Phone 8 devices
Use Windows RT platform
Pros
Enables targeting of Windows and Windows Phone
Takes full advantage of new APIs and platform
capabilities
Better performance & reduced memory use
Cons Will not run on Windows Phone 8 devices
45. Primary features:
Existing Windows Phone 8 apps run flawlessly
Windows Runtime XAML platform and HTML/WinJS support brings convergence with Windows
8.1, and is faster and uses less memory than Silverlight
The core of an app can be built once for Windows and Windows Phone; you can share elements
of UI, though it’s best to tailor the user experience for each platform
Convergence is not just in the developer platform: it spans tools, store, commerce
Developer investment in the existing Silverlight platform is protected: Existing Silverlight apps can
be upgraded to access new Windows Phone 8.1 platform capabilities
Now is the time to build for Windows and Windows Phone!
