The document discusses advancements in the Windows platform from 2005 to 2014, focusing on the development of universal Windows apps that enhance user engagement across multiple devices. It highlights the tools and frameworks available in Visual Studio for developers, including shared projects and improved background task models, while emphasizing API convergence and a common user experience. Furthermore, it provides resources for developers to build and optimize applications for both Windows and Windows Phone.

4. Windows brings apps to life
Windows provides apps with more ways to engage users,
both on device and across all of their Windows screens
Design once to engage everywhere
Developers can use universal Windows apps to design an
one app that can target every Windows screen
Build faster with Visual Studio
New shared projects for Universal Windows apps allow
developers to share as much or as little between Windows
and Windows Phone projects

5. Converged web browser
• WP 7.5 shipped with IE9
• Same rendering + JavaScript engine
Aligned user experience
• Modern UI on WP + Xbox 360
Aligned dev platform
• Games: DirectX; XNA
• Apps: XAML + XAML (WPF; SL)
Converged core (NT kernel)
• Common kernel & file system
• Converged driver model
• Converged networking stack
• Secure boot & storage encryption
(BitLocker)
Aligning user experience
• Live tiles on Windows
Aligning the dev platform
• Aligned UI frameworks:
XAML; DirectX; C++
• Converged API for sensors & IAP
• Converged Web Browser: IE10
Converged dev platform
• Converged WinRT app model
on Windows, Windows Phone, Xbox
• Converged roaming + credentials
• Better HTML5/web support via IE
Aligning the Stores
 Aligned processes and policies
 Shared dev registration
• Shared entitlement
Improved App Experience
• Proximity & location frameworks
• Security & identity
• Background execution

6. | |
A converged developer platform enables you to do more with the same code and skillset

7. Universal Windows apps
• One Visual Studio solution with three nodes
• Two UI node (One for phone; one for client)
• One shared code node (WinRT apps only)
Linked apps
Devs can be link their Store apps using a common
PFN (Product Family Number) across client + phone
New tooling and app linking makes it easy to engage everywhere

8. Visual Studio streamlines developing universal
Windows apps

9. You can tailor the design to each device

11. Shared projects to build universal apps
• One shared project solution in Visual Studio
• Project creates two AppX packages (one per Store)
• Shared dev and test tooling for both platforms
IDE improvements

12. C#
#if WINDOWS_PHONE_APP
Windows.Phone.UI.Input.HardwareButtons.BackPressed +=
this.HardwareButtons_BackPressed;
#endif
C++
#if WINAPI_FAMILY==WINAPI_FAMILY_PHONE_APP
_backPressedEventToken = HardwareButtons::BackPressed +=
ref new EventHandler<BackPressedEventArgs^>(this,
&NavigationHelper::HardwareButton_BackPressed);
#endif

15. Portable
Class Libraries
I compile just once
and know it works
on all platforms
Shared
Projects
I can easily include
platform-specific code
under #if or partial
classes
New! Improved!

16. Windows Runtime (WinRT) is the shared
runtime and API space used across
the Windows platform (phone + client)
API coverage for Store app scenarios
• In 8.0, we had ~30% API convergence
 In 8.1, we move well past 90%+ convergence
 Common contract support now converged:
Launch; Share; CachedFileUpdater; FilePicker
 Most non-converged APIs are form-factor specific
(SMS/phone calls; Direct Access)

17. Keep using Windows Phone Silverlight 8.0 / 8.1 for these features / apps

34. Converged background task model
• Improved background agents make your app more agile
• New triggers and conditions increase user engagement
Background agent improvements
New trigger-based execution options

36. A single place for all your missed notifications
 FIFO processing
 Limit of 20 notifications per app

40. Start screen backup
Configuration data can roam with the user
• Sync engine transfers data periodically based on triggers
(user idle, battery, network, etc.)
• Syncs up to 100kb of data using the app’s PFN
• Data is stored in the user’s OneDrive account,
but doesn’t count against their OneDrive quota
Application data can be backed up
Data is backed up daily in user’s SkyDrive account per device, and counts
against their OneDive quota
(user can disable)
