building universal windows apps for smartphones and tablets with xaml & c#
DESCRIPTION
This session is your fast track into the wonderful new world of app development for Windows device. Come learn how your valuable C# skills now make you a hot mobile developer for smartphones, tablets, laptops and desktops. We’ll perform a quick lap around Microsoft Visual Studio 2013 and the new Windows Universal Apps, build our first app using XAML & C#, and debug it with Windows 8.1 and the Windows Phone Emulator. We’ll then explore the converged WinRT API services and features, such as touch input, accelerometers, Live Tiles, etc. We’ll also spend valuable time going over the new app model for Windows device apps, how to share code between phone and tablet, and how to build a converged UI in XAML for Windows 8.1 and Windows Phone. Lastly we’ll go over the app packaging and how to submit your Universal apps to the Windows Store. The converged Windows Platform is more efficient and far-reaching than ever. Come learn how to build mobile apps for hundreds of millions of Windows device users.TRANSCRIPT

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

A converged developer platform enables you to do more with the same code and skillset
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 appsDevs 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
Visual Studio streamlines developing universal Windows apps
You can tailor the design to each device
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
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
PortableClass Libraries
I compile just onceand know it works
on all platforms
SharedProjects
I can easily include platform-specific code under #if or partial classes
New! Improved!
Windows Runtime (WinRT) is the shared runtime and API space used acrossthe 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)
Keep using Windows Phone Silverlight 8.0 / 8.1 for these features / apps

Windows uses a virtual layout canvas to enable your app to light-up the experience most appropriate to the screen
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

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 upData is backed up daily in user’s SkyDrive account per device, and counts
against their OneDive quota
