4. Application Performance
Startup is *the* chance to lose users
Invested heavily in startup time for Windows Phone 8
Facebook app reduced from 12 seconds to 4 seconds
Why?
Execution environment improvements
Compile in the cloud
Core CLR improvements
Dual core >1ghz is a wonderful thing 

5. Introducing: Compile in the cloud
Moving to CoreCLR brings Native Image Generator (NGEN)
Expensive and time consuming on device
Compile in the cloud NGEN’s your code when you submit
Submit your XAP to marketplace just as you did in 7.x
Code in XAP is NGEN’d and the XAP updated with compiled code
What about my existing app?
7.5 apps are NGEN’d so Windows Phone 8 gets compiled version
Original 7.5 apps is kept for download to 7.5 devices

6. Performance is much an art as it is science
Users care about perceived performance not benchmarks
Key Performance Indicators
How often you use the app really impacts your feel for performance
4 seconds is still too long for the app you use all the time
Perception is impacted by context switching
Even if your app starts super fast if the user has to remember where they were it slows them down

7. Resuming applications
In 7.5 we allowed apps to be in a suspended state
This is great but…
Only get the benefit if you tap back or use the task switcher we resumed the apps
Task switcher isn’t a feature that every user will use

8. Introducing: Fast App Resume
Allows your app to always resume no matter where it’s launched from:
App list
Live Tile
Toast
Deep link
If your app is in the back stack then we will resume it
If it’s not then we will launch a new instance

9. Demo

10. Enabling FAR in your app
Not enabled by default. Why?
Protect your user experience
Ensure that apps don’t break
Very simple to enable
New ActivationPolicy attribute on DefaultTask
<DefaultTask Name="_default" NavigationPage="MainPage.xaml" ActivationPolicy="Resume"/>
Go to Session (Thursday 8:30 am!) for more details on this

11. Multitasking

12. Background Location tracking apps
Location tracking apps are pretty limited if they can’t keep running
Enables your app to continue running in the background *if* it is actively tracking location

13. How to enable
<DefaultTask Name="_default" NavigationPage="Views/Home.xaml">
<BackgroundExecution>
<ExecutionType Name="LocationTracking" />
</BackgroundExecution>
</DefaultTask>
Go to Session (Thursday 8:30 am!) for more details on this

14. Demo
Background location

15. Maps
Bing Maps control from Windows Phone OS 7.1 is still supported, but deprecated
The new Maps controls use technology supplied by Nokia
New features:
Vector-based for faster rendering
Four cartographic map modes
Light and dark color modes
Display landmark and pedestrian features

16. Integrating with the phone

17. VOIP Provide platform for *all* VOIP providers
Integrate with phone incoming call notification
Enable Video calls
Enable background audio calls
Enhanced push notification support

18. Demo
Skype

19. App Deep Linking and Sharing
Custom Schemes
First PDC 1996 (the PDC with Steve Jobs!)
Ability to register a custom URIs for your app
skype:andrewclinick – starts a conversation with me
fb://profile/ – brings up my profile
Allows for browser integration
Allows for rich integration between apps
File Types
Register your own file type
Goto (Friday 12:45) for deep dive on this

20. Make a Skype call Peter Bergman Skype:PeterBergman
Loved the Purple Onion

21. Data

22. Data Storage Structured Data SD Card
SQL Server and L2S still supported
Lots of feedback that you were looking for alternatives
Worked closely with SQLite
SQLite is available TODAY for Windows Phone
SD Card
Read Write to the SD card

23. Device Data Apps can create contacts visible in the People hub
Read/write access to app’s own contacts
Read-only access to other contacts if allowed by owning app (same as Mango)
create_task(ContactStore::CreateOrOpenAsync())
.then([] (ContactStore^ store) -> IAsyncAction^ {
StoredContact^ george = ref new StoredContact(store);
george->Description = "George Mallaley";
george->GivenName = "George";
george->FamilyName = "Mallaley";
auto props = create_task(george->GetPropertiesAsync()).get();
props->Insert(KnownContactProperties:: ,
return george->SaveAsync();
});

24. Live Apps

25. Tile Templates and Tile Sizes
Windows Phone 8 supports three Tile templates
Flip – flips from front to back (similar to the WP 7.1 Tile template)
Iconic – clean iconic layout designed to reflect Windows Phone design principles
Cycle – cycles through up to nine images 25

26. Lock Screen on Windows Phone 8
You can register your app as a lock screen provider, which enables:
User can select your app to show detailed status on the lock screen
Can select your app as one of the five apps to show quick status (icon and count)
Can select your app as the lock screen background image provider

27. Lock: dynamic wallpapers – how it works
Activate via Lock+Wallpaper CPL or within app
Update the wallpaper
When the app is running
Using a background agent
New Shell APIs
ShellSetWallpaper to use a new image
ShellWallpaperSchedule to download a single image from the internet on a specific interval (e.g., 30 mins, 1 hour, etc.)
ShellWallpaperFolderSchedule to cycle through a set of image in app’s isolated storage (e.g., a photo slideshow) based on number of views of the lock screen

28. Demo
Facebook

29. Enterprise

30. Enterprise Device management App deployment
Enroll device with management server (inTune etc)
Set policies to be applied and updated
Automatically keep apps updated
App deployment
No need to deploy apps into Windows Phone Store
Deploy using the technology that makes sense for your company
Apps signed by you are deployable via web, or app
Go to :30) for more Enterprise info

31. Demo
Company Hub

32. Why Enterprise deployment matters to you
Flexible deployment allows for considerable benefits
Testing apps
Uses company hub to distribute latest builds of your app to you testers
Beta apps in the marketplace work great but not suited to daily builds
& SD card deployment allow for “sneakernet” simplicity

33. Summary Significant application runtime improvements
Fast App Resume helps every app
Multitasking improvements enable key new app experiences
Live Tiles provide significant user experience advances
Lockscreen and notifications allows you to build deeper integration
Enterprise deployment allows for considerable flexibility
