This document discusses connecting Windows Phone 7 applications to cloud services using Windows Azure. It covers storing and sharing data in Windows Azure Tables and SQL Azure, synchronizing data using Sync Framework 4.0 CTP, using push notifications to enable cloud-initiated communication, and the Windows Azure Toolkit for developing Windows Phone 7 applications. A number of demonstrations are provided to illustrate these cloud integration capabilities with Windows Phone 7.

2. AGENDA
• Connect a phone with a Cloud // no need to call mom
• Store data in Windows Azure Tables
• Sync data with a Cloud or SQL Server
• Build responsive phone client // you better call your mom
• Push notifications
• Windows Azure Toolkit for Window Phone 7

3. WELCOME TO UNLIMITED WORLD
PHONE CLOUD
• Connected • Common endpoint
• Pervasive • Scalable
• Marketplace • „Pay as you go“
They make a great team!

4. WHAT’S IN COMMON?
• Common development tools
• Emulator for development
• Complementary application models
• Phone: somtimes on, connected
• Cloud: always available, running

5. PHONE-INITIATED COMMUNICATION
• HTTP-based, request/response
• Framework choices (WCF, OData, WebRequest, …)
• Wire format choices (SOAP, JSON, POX, …)

6. Simple Client/Server application
DEMO

7. STORING AND SHARING DATA
• SQL Azure
• Familiar relational database
• Highly available, managed for you
• T-SQL
• Windows Azure Tables
• Non-relational structured storage
• Scale-out, billions of rows
• OData
• Windows Azure Blobs
• Big files
• REST

8. “HOUSTON CAN YOU HEAR ME?” KHHHKK…
“…I think we lost the signal”
• Phone is occasionally connected
• Synchronize data, cache locally
• Sync Framework 4.0 – CTP
• Sync with SQL Server or SQL Azure
• Silverlight, Windows Phone 7, HTML 5, …
• Sync logic on the server, think clients

9. Using Windows Azure Tables &
Sync Framework 4.0 CTP
DEMO

10. WHEN AN APP LOOKS MORE LIKE A COMIC
• Put long running operations in a
background thread
• Prevent doubling
• Don’t wait for data
• Reactive Extensions
• LINQ based queries
• Subscriptions
• Async & Events

11. Reactive Extensions
DEMO

12. CLOUD-INITIATED COMMUNICATION
• Push notifications
• Single connection between phone and Microsoft Push
Notification service
• Bandwidth- and battery-friendly
• Delivery not guaranteed
• Three kinds of push notifications:
• Raw – message to application
• Toast – message to user
• Tile – image, title, count

13. PUSH NOTIFICATIONS
1. Phone opens a channel
2. Phone sends URL to cloud 1
3. Cloud pushes notifications 4
to MPNS
3
4. Microsoft Push Notification
service notifies phone

14. IS THERE ANY FASTER WAY?
• Windows Azure Toolkit for Windows Phone 7
• Proof of concept
• ASP.NET MVC 2 (as a Web role)
• Windows Phone 7 application
• “Getting started” guide
• Hire me 
