App Model: Concepts
Application
Uniquely identifiable,
licensable and serviceable
software product
packaged as a XAP
Application
Deployment
Windows Phone
Marketplace
Steps include Ingestion,
Certification and Signing
Application license
Crypto-verifiable object
issued to grant rights to
an application
Windows Phone
Marketplace
App Lifecycle
Windows Phone
Marketplace
+
Phone only installs .xap packages signed by marketplace
Phone handles all aspects of .xap installation based on the manifest

Individual apps cannot make arbitrary changes to the phone during installation
Users control install, update and uninstall, while the marketplace controls
revocation

Individual apps do not control their own lifecycle on the phone
App Isolation and Execution
Applications
and licenses
Application
install folders
Running
applications
Phone only runs apps that have a valid marketplace license
Apps are sandboxed into separate security accounts while installed and at runtime
Resource allocation policy keeps the foreground app responsive
Resource management policy ensures the user can always use Start to run a new
app

Each app executes inside an isolated, least-privileged host process
All app code is transparent and CLS-verifiable, mitigating impact of common attacks
Frameworks enable app code to interact with app model, UI model, phone functionality

UI
Model
UI Model: Concepts
Application
UI and logic for
functionality exposed
through pages
Page
A single screen of user
interaction elements
Session
An ordered workflow of
user interactions
spanning applications
UI Model: Familiar Web Concepts
Phone application
Web application
Provides UI represented as
XAML pages connected into
cross-app flows by URI’s
Provide media represented
as HTTP resources linked
by URL’s
Shell frame
Web browser
Requests pages, renders UI, and
handles navigation across apps
Requests HTTP resources,
renders them, and handles
navigation across sites
Sessions and back stack
History and tabs
Groups together sequences of
pages corresponding to a user’s
activity across apps
Groups together sequences of
HTTP resources corresponding
to a user’s activity across sites
UI Navigation: Example
Pictures
Take a look at
recent photos
People
Look up the status
for a contact
Pictures
Continue looking
at recent photos
Active
sessions
UI and State Management: Concepts
Discarded while the session is
paused
Page UI
Describes the visual
appearance of a page
Page State
Contains data that
describes an instance of
a page, analogous to
browser cookie
Retained in shell frame to support
resuming paused sessions
UI and State Management: Example
Running Applications
Dehydrated and
rehydrated on demand
from saved state
Shell Frame
Monitors resource
usage to decide when to
pause sessions
Apps restarted and UI rehydrated as
the user navigates thru the phone
DEMO: UI MODEL
Graphics Composition
Shell frame composes all UI into a single screen
Central page management enables cross app UI transitions and other effects
System wide Z order enforcement emphasizes core phone functionality
