2 fine print  Not “Silverlight 101”  Lots of resources on-line to learn  Watch Shawn Oster’s talk on-demand  More in-depth information from Istvan Cseri’s talk  Tomorrow morning

3 key take-aways  Applications are built using pages  UI is clean and simple  Services enhance the user experience

4  Peter (part 2)  Application structure  Controls & theming  Connected services  Mike (part 1)  Introduction  Output  Input  Web Browser  OS App Integration building applications, parts 1 & 2

Demo application structure

the back key

11 back key details  Lets the user to return to previously- viewed screens  Can go back across applications  Not used for application-specific behaviour

Demo back button (the exception that makes the rule)

13 a world of constant interruptions phone calls App switch txt msgs :-) reminders low battery lock screen

14 Not running StartRunningExit basic application lifetime Obscured Paused

15 obscured: popup ui from shell RunningObscuredRunningUnobscured Games could auto- pause Game could auto-resume Phone call Reminder Battery low Not in the Mix build

16 paused: jump to another app RunningPauseSuspendedResume Assume your process is killed Save state for later use Load state to continue where you left off Not in the Mix build User never knows what happened :-) Start Button Accept call Open toast

17  Peter (part 2)  Application structure  Controls & theming  Connected services  Mike (part 1)  Introduction  Output  Input  Web Browser  OS App Integration building applications, parts 1 & 2

18 default control templates  Simple and elegant  Over-sized hit targets  Use of transparency  Watch Michael Smuga’s design talk online!

19 theming  Enables user to personalize their phone  Dark and light themes, each with several accent colours  Built-in controls are automatically themed

Demo case study:

21 available controls  Core controls delivered in-ROM  Button  CheckBox ……  Thinking about future controls releases  Let us know what to focus on first!

22 a note on screen resolution  Single hardware & software platform  Two screen resolutions  Applications must support both  Updated tools will be available before phones hit the market
