Performance
Application PerformanceStartup is the chance to lose usersWe invested heavily in startup time for Windows Phone 8Facebook app reduced from 12 seconds to 4 seconds
Why?Execution environment improvementsCompile in the cloud Core CLR improvements
No work from developers – free (as in beer)!
Compile in the cloudMoving to CoreCLR brings Native Image Generator (NGEN)Code generation is expensive and time consuming on deviceCompile in the cloud NGEN’s your code when you submitSubmit your XAP to marketplace just as you always haveCode in XAP is NGEN’d and the XAP updated with compiled code
What about my existing app?7.1/7.8 apps are NGEN’d so Windows Phone 8 gets compiled versionOriginal 7.1 apps is kept for download to 7.1 devices
Performance is as much an art as it is a science
Users care about perceived performance not benchmarksKey Performance IndicatorsHow 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
Resuming applicationsIn 7.5 we allowed apps to be in a suspended stateThis 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

Fast App Resume
Evolution of Multitasking
What is Fast App Resume?
Fast App Resume UX
Resume previous experience for Primary tilewhen previously launched via Primary tile
Start fresh for Deep Linkswhen previously launched via Primary tile or a different Deep Link
Don’t block OnBackKeyPressthis is how users close your app
Fast App Resume Basics
“Replace” is the default activation policyOpt-in to “Resume" via manifest setting<DefaultTask Name="_default" NavigationPage="MainPage.xaml" ActivationPolicy="Resume" />
Apps are still suspended or tombstoned
Fast App Resume In The Real World
Backstack – Do nothing
Backstack – Clear page stack
Reset: Clear the page stack
Backstack – Clear page stack
Backstack - Cancel navigation

Fast App Resume Code Demo
Fast Resume TakeawayMain Tile: Resume!Deep Links: Clear the back stackOnBackKeyPress: Do not block Test relaunch: between primary tile and deep linksDon’t forget Tombstoning!
Integrating with Windows Phone
App Launching with URI and File AssociationURI AssociationFirst introduced @ PDC 1996 (the PDC with Steve Jobs!)Ability to register a custom URIs for your app• skype:Call?UserID=thomasfennel – starts a conversation with me in Skype• fb:Profile?UserName=thomasfennel – brings up my profile in FacebookAllows for browser integrationAllows for rich integration between apps
File AssociationRegister your own file type
Go to Sean McKenna’s Session (2-212) Friday @ 2PM

Tile Templates and Tile SizesWindows Phone 8 supports three Tile templatesFlip – 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 30
Your app can show detailed status on the lock screenYour app can show quick status (icon and count)Your app can update the background image
Lock Screen on Windows Phone 8
Lock: dynamic wallpapers – how it worksActivate via Lock+Wallpaper CPL or within app Update the wallpaper When the app is running
Using a background agent
New WinRT APIs
Go to my session (2-206) Thursday @ 11.30AM
Enterprise
EnterpriseDevice managementEnroll device with management server (inTune etc)Set policies to be applied and updatedAutomatically keep apps updated
App deploymentNo need to deploy apps into Windows Phone StoreDeploy using the technology that makes sense for your companyApps signed by you are deployable via web, email or app
Why Enterprise deployment matters to youFlexible deployment allows for considerable benefits Testing appsUses company hub to distribute latest builds of your app to you testersBeta apps in the marketplace work great but not suited to daily buildsEmail & SD card deployment allow for simplicity
With great power comes great responsibility…
SummarySignificant application runtime improvementsFast App Resume helps every app – go do it!Multitasking improvements enable key new app experiencesLive Tiles provide significant user experience advancesLockscreen and notifications allows you to build deeper integrationEnterprise deployment allows for considerable flexibility
