PerformanceSlide10

Application Performance

Startup is

the

chance to lose users

We 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

No work from developers – free (as in beer)!Slide11

Compile in the cloud

Moving to

CoreCLR

brings Native Image Generator (NGEN)

Code generation is 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

always have

Code 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 devicesSlide12

Performance is as much an art as it is a 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 downSlide13

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

useSlide14

Fast App Resume

Evolution of MultitaskingSlide16

What

is

Fast App Resume?Slide17

Fast App Resume

UX

Resume previous experience for Primary tile

when previously launched via Primary tile

Start fresh for Deep Links

when previously launched via Primary tile or a different Deep Link

Don’t block

OnBackKeyPress

this is how users close your appSlide18

Fast App Resume

Basics

“Replace” is the default activation policy

Opt-in to “Resume" via manifest setting

Integrating with Windows PhoneSlide28

App Launching with URI and File Association

URI Association

First 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 Association

Register your own file typeGo to Sean McKenna’s Session (2-212) Friday @ 2PMSlide29

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

30Slide31

Your app can show detailed status on the lock screen

Your app can show quick status (icon and count)

Your app can update the background image

Lock Screen on Windows Phone 8Slide32

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

EnterpriseSlide34

Enterprise

Device management

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 companyApps signed by you are deployable via web, email or

appSlide35

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

Email & SD card deployment allow for

simplicity

With great power comes great responsibility…Slide36

Summary

Significant application runtime improvements

Fast App Resume helps every app

– go do it!

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 flexibilitySlide37
