6. Platform Compatibility
o WP7 and WP7.1 Apps run on WP8!
o No general breaking changes
o Existing code is emulated in Quirks-
Mode
o Some API differences
example:
XmlSerializer
WP8 must have a default constructor.
WP7 quirks: It is not necessary to have a default
constructor
o Code after Rebuild targets WP8 platform

7. The dream or reality?

8. Upgrade
o In Solution Explorer, use the Upgrade
to Windows Phone 8.0 command.
o In the project designer, change the
Target Windows Phone OS Version
value to Windows Phone OS 8.0.

20. Your Apps Your way

21. Supported Languages

22. Project Templates
o C# (HTML5)
o XNA
o C++
o HTML5

23. Demo
Windows Phone 8
JavaScript
Web App
jQuery
on Phone

24. Threading
o OS 7.1, apps run on a single core, and
the scheduler is less aggressive in time-
slicing
o OS 8, apps run on multiple cores and the
scheduler is more aggressive in time-
slicing threads.
Raise conditions and concurrency bugs
easier to achieve 

25. Platform Targeting
o Single OS 7.1 version which runs on
both. No new features are supported.
Runs in quirks
o Create separate copy for 7.1 and 8.0
o Create separate copy with shared files

26. Demo
Windows Phone 8,Windows 8
Code Sharing
Portable
Linked Files
Library
Camera Accelerometer

27. Network Improvements
o Socket Listeners (Incoming)
Windows.Networking.Sockets
o IPv6
o Winsock Support
o Proximity API
