Windows 8
Installation von Apps
Store anatomy
Windows Store app acquisition
Building blocks of an app package
App Manifest contains all information needed to deploythe app
Blockmap contains hashes of all files within the app package
Signature validates the integrity of the app package
App manifest and capabilities
Explicitly declares the app integration endpoints
File capabilities (music/pictures/videos/documents libraries, removable storage)
Devices (webcam, microphone, location, sms, proximity); extensible to new device classes
Network and identity (internet, private network, credentials)
File type associations
App contracts (search, share, etc.)
Contained in appxmanifest.xml; Visual Studio provides editor
Ausführung
Process state transitions
App gets 5s to handle
suspend
App is not notified
before termination
Apps are notified
when they have been
resumed

Implementing Search
Search Anatomy
1. Search box is scoped to the main app on screen
2. Query suggestions provided by the main app on screen•Autocompletes to terms for
which the app has search results
3. List of installed Metro style apps that have implemented the search contract
4. Result recommendations•Must include a thumbnail and title
• Indicates a strong or exact match result
•Takes users directly to the details of the result
5. Results•Show the count or not found
•Be pertinent
•Allow search refinement
with filters for example
Search Anatomy
Implementing Search
• Search contract sample (Windows SDK)
Implementing Share
Informationen teilen
Quell-App bietet Informationen zum Teilen an
Quell-App muss Ziel-Apps nicht kennen
Ziel-App empfängt Informationen und verarbeitet diese
Ziel-Apps muss Quell-Apps nicht kennen
Windows 8 orchestriert Kommunikationsfluss
Apps kommunizieren nicht direkt miteinander
Sharing From Source to Target
User selects “Share”,
active app is sent event
Activated for sharing
Registers with the
DataTransfer Manager
Filters list of Target
Apps and Quicklinks
User selects Target

Custom data formats
Implementing Share
• Sharing content source app sample (Windows SDK)
• Sharing content target app sample (Windows SDK)
Live Tiles
Basic Tiles
Tap on tile to launch or switch to an app
Static default tile specified in app manifest
Both sizes can have live updates Square (1x1) Wide (2x1)
Live Tiles
Notification Queuing
Secondary Tiles
Live Tiles
• App tiles and badges sample (Windows SDK)
• Secondary tiles sample (Windows SDK)
Toast Notifications
Toast Notifications
Toast notifications deliver
transient messages outside the
context of the app
Use toast notifications to get
user’s attention immediately
User is in control and can
permanently turn off toast
notifications from your app
Allows quick navigation to a
contextually relevant location in
your app
Toast notifications are easy to
invoke from your app or from
the cloud
Toast Templates
Toast notifications use the same
template architecture as Live
Tiles
Rich set of rendering options
available
Toast Notifications
• Scheduled notifications sample (Windows SDK)
• Toast notifications sample (Windows SDK)
Windows Notification Service(WNS)
Windows Notification Service
Enables delivery of tile and toast notifications over the internet.
Tile updates and notifications shown to the user even if your app is not running.
WNS handles communication with your app
Scales to millions of users
WNS is a free service for your app to use
Push Notification Overview
1. Request Channel URI
2. Register with your
Cloud Service
3. Authenticate & Push
Notification
Stay Connected
• Background task sample (Windows SDK)
• Push and periodic notifications client-side sample (Windows SDK)
• Raw notifications sample (Windows SDK)
• Windows Azure Mobile Services
What is Windows Azure Mobile Services?
Key ScenariosWindows Azure Mobile Services are ideal for:
Structured Storage
Structured Storage with SQL Database
If using single database apps are partitioned by schema
AppX.Todoitem
AppY.Todoitem
Manage data in
Portal
SQL Portal
SQL Management Studio
REST API…
Server Logic
Automatic service REST API generated for
storage
Dynamic Schema on/off
Ability to author server logic that intercepts
CRUD operation pipeline
Rich querying capability
Server Logic
Supported Modules + Globals
mssql
request
console
push
tables
statusCodes
mssql.query('select top 1 * from statusupdates',
{ success: function(results) {
console.log(results);
}
}
);
REST API to SQL type mappings
JSON Value T-SQL Type
Numeric values (integer, decimal, floating point)
Float
Boolean Bit
DateTime DateTimeOffset(3)
String Nvarchar(max)
Push Notification Lifecycle Overview
1. Request Channel URI
2. Register with your Cloud Service
3. Authenticate & Push Notification
Push Notifications
Integrates with WNS to provide Toast, Tile and Badge notifications
Portal captures your WNS client secret and package SID
push.wns.* provides:
clean easy object model to compose notifications
Performs auth against WNS for you
Auth*
Authenticate against Windows Live
Table level permissions for each CRUD operation
Everyone
Anyone with the Application Key
Only Authenticated Users
Only Scripts and Admins
More granular control with server side scripts
user.level: {admin, authenticated, anonymous}
user.userId: id or undefined if not authenticated
