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
20. 20
Windows Phone 7.5 Windows Phone 8.0
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
21. 21
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

system that extends along the x and y
axis into infinity, allowing you to scale

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
34. Action Center
• Central location to surface
missed notifications
• Apps can intelligently manage
notifications
(silently add, update, and delete
notifications)

39. Anna beats a level, with top
score!
The app asks her if she wants
to share this with her
friends? She says – “yes
please!”
Congratulations!
Shall we share this?
Share on:
Anna is playing her favorite
game. The level is almost
over, and Anna could break
her record. The application
starts recording the screen.
The application uploads the
MP4 file, which was
automatically transcoded to a
VGA resolution for quick
uploading, to a website for
sharing.
43. Internet Explorer 11 brings more life to the mobile web via better HTML5 support

Ability to code pinning behavior
• Specify high-resolution site icons
• Live tiles using notifications
Professional quality video
• 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
Rich user interactions
• Screen + device orientation APIs
• Pre-fetch and pre-render
50. Supported operating systems Windows 8.1 (x86 or x64)

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 XAML 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
58. 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
