Windows Store app acquisition
Building blocks of an app package
 App Manifest contains all
information needed to deploy
the 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

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
Search Anatomy
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
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

 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)

Toast Notifications
Toast Notifications
 Toast notifications deliver
 Allows quick navigation to a
 Use toast notifications to get
 Toast notifications are easy to
transient messages outside the
context of the app
user’s attention immediately
 User is in control and can
permanently turn off toast
notifications from your app
contextually relevant location in
your app
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

Windows Azure Mobile Services
What is Windows Azure Mobile Services?
Key Scenarios
Windows 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
mssql.query('select top 1 * from statusupdates',
 request
{ success: function(results) {
console.log(results);
 console
}
 push
}
);
 tables
 statusCodes
REST API to SQL type mappings
JSON Value
Numeric values (integer,
decimal, floating point)
Boolean
DateTime
String
T-SQL Type
Float
Bit
DateTimeOffset(3)
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
