Bringing one Windows to developersWindows 8.1 provides developers with a shared platform that renders the right app experience for the right form-factor

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

Designed once; engaging

everywhere• Converged developer platform• Converged app model• Shared app identities + entitlement• Unified push services (via WNS)

Platform convergence is a journey…Windows Phone 7.5 Windows Phone 8.0 Windows Phone

8.1Convergence Begins with IE

• WP 7.5 shipped with IE9

• Same rendering engine as Windows

• Same JavaScript engine as Windows

Converged Core (NT kernel)

• Common kernel & file system

• Kernel mode driver framework

• Secure boot & storage encryption (BitLocker)

• Core networking stack

Developer Platform

• Partial API convergence (focus on sensors & IAP)

• Native Code (C++) and DirectX

• IE10

Converging the 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

12

API convergence across the Windows platform

CommonWinRT APIs

Phone-specificWinRT APIs

Windows-specificWinRT APIs

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

What’s new for developers in Windows Phone 8.1A summary of the stand-out features for developers

17

Developers can create a single app that targets Windows Phone and Windows

• One Visual Studio ‘Universal app’ project template for your app

• Shared dev and test tooling for both platforms

Converged Windows XAML Apps

18

Developers can use their HTML/CSS and JavaScript skills to create native apps that run on Windows Phone, similar to Windows

• Not covered in this Jump Start

Screen Recorder: Record while you Play

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.

* Screen recording available on Windows Phone only
