Two part sessionThe basics

Build app from File -> New…Advanced tips and tricks

Silverlight

Modern XAML/event-driven application UI frameworkRapid creation of visual stunning applicationsMetro-themed UI controls500,000 developers spanning Windows and web

XNA

High performance game frameworkRapid creation of multi-screen 2D & 3D gamesRich content pipelineMature, robust, widely adopted technology spanning Xbox 360, Windows and Zune

XNA/Silverlight Interop

silverlight for windows phone

Silverlight for Windows Phone is…Silverlight 3minus a few things that didn’t make senseplus a few Silverlight 4 things that didplus phone specific API & “under the hood” improvements

Silverlight 4 compatibility (1500+ new APIs)

Getting started…

demo

navigation

Applications are built like web sitesFunctionality is split into pagesForward navigation via linksBackward navigation via Back

Previous applications (pages) are in the back stackCan override back button behavior (but be careful)

Transient pages

Payload can be send with navigation request

NO back to home buttons!!!

Deep linking

Navigation

demo

familiar web concepts

Phone applicationProvides UI represented as XAML pages connected into cross-app flows by URI’s

Web applicationProvide media represented as HTTP resources linked by URL’s

Shell frameRequests pages, renders UI, and handles navigation across apps

Sessions and back stackGroups together sequences of pages corresponding to a user’s activity across apps

Web browserRequests HTTP resources, renders them, and handles navigation across sites

History and tabsGroups together sequences of HTTP resources corresponding to a user’s activity across sites

launchers and choosers

Windows Phone execution model isolates every application in its own sandbox

Apps cannot directly access information stores such as contactsCannot directly invoke other applications such as phone or messaging

Launchers and Choosers allow applications indirect access to the useful phone featuresLaunchers and Choosers APIs invoke distinct built-in applications that replace the currently running applications

launchers and choosers

LauncherLaunches one of the built-in applications though which a use completes a taskNo data is returned to calling applicationExample: PhoneCallTask

ChooserLaunches one of the built-in applications through which a user completes a task and which returns some data to calling applicationWhen caller completes, calling application is activated and supplied with the Chooser resultExample: PhotoChooserTask

choosers and the execution model

IMPORTANT! When you launch a Launcher or Chooser, your app is terminated

When task completes, your app may be reactivated and a new app instance created (SOMETIMES)

The following choosers and tasks have relaxed thombstoning policy

panoramas

panoramas

pivots

panorama vs pivot

Pivot

Filter same data on different views (the “inbox” is a great example of this) Optimized for current screen size Filter of data doesn’t have to be same view (agenda/day) Related content is ok to pivot on as long as related content is truly related Focused “Virtualized”

Panorama

Horizontal broad canvas, not confined to current screen size A ‘top layer’ view into underlying experiences/tasks Use white space Performance -> Panorama loads all the pages on startupExploratory in nature

Adding and using the Pivot

demo

misuse of common controls

Use the WP7 common controls appropriately.

Don’t use sliders, toggles or map controls under panoramas or pivots –as they both need the same gestures to work.

MVVM phone style…

demo

networking on the phone

Support for networking featuresWCF/ASMXHttpWebRequestWebClientNo cross-domain policy file required

Not supportedSocketsCustom WCF BindingsWCF RIA ServicesNTLM authentication

WCF/ASMX services

Can “Add Reference” from Windows Phone projects to automatically generate proxy classes

ASMX should just workWCF requires that you use basicHttpBinding

OData

Server:WCF Data Services provides an extensible tool for publishing data using REST based interface

Publishes and consumes data using Odata web protocolFormat is XML or JSON

Client:Download Odata Client Library for Windows Phone

http://odata.codeplex.com/

FULL parity with Silverlight (Including LINQ and Add Service Reference support)

Getting data

demo

HTTPWebRequest vs WebClient

Use HttpWebRequest whenever possibleUse background thread and marshal back to UI thread (Using Dispatcher.BeginInvoke)

WebClient is “easier” to use but happens on the UI thread no matter where it was spawned (Bug)6 Parallel requests limit

WebClient bug fixed

marketplace

Enhanced DiscoveryEasy to find great applications & gamesFun to browse the marketplace

Simple & Reliable AcquisitionTry before you buyBuying and downloading content is a breezePayment flexibility (Monthly billing and credit card)Easy application updates

South Africa WILL BE supported…

marketplace

It costs nothing to download the Windows Phone SDK and write code using the emulatorTo sell applications you need to register as a developer

This costs $99 a year and allows you to publish any number of fee applications and up to 99 free applications

Each additional application costs $20

Students can sign up for freeRevenue sharing (30/70)

yalla apps
