Runtime 8 provides a common application programming interface and runtime across Windows 8, Windows Phone 8, and Windows Server 2012. It allows developers to write code once and deploy it across these platforms, simplifying development. Some key aspects of Runtime 8 include a new type system, app deployment options through the Windows Store or sideloading, and common APIs for networking, sensors, storage and more. It aims to unify development across platforms.

5. Why new Runtime?

6. Demo
P=U*I
List<>.Add()
new Thread().Start()
ThreadPool.RunAsync()

7. Stubs, no pInvoke!
CLR WinRT
RCW CCW
WinRT Managed
Object Object

8. Stub Samples

9. New Type System
o Standard Types
o Windows.*
o Primitive Types
o Byte, Int32, ..
o Marshaling required:
o String, Object
o Projected Types
o Windows.Foundation.Uri
o Windows.Foundation.DateTimeOffset
o HRESULT
o Projected Interfaces
o IVector<T>,
o IMap<T>
o Helpers
o StorageFolder.OpenStreamForReadAsync(fileName);

10. Demo
As Runtime
(Store App)
WinRT
As API
(Desktop App)

11. App Deployment
o Two options
o App Store
o Sided Loading (for Enterprises)
oExplicit Installation
oProvisioning

12. Sided Loaded Apps
(none appstore deployment)
o By Group Policy
If in Windows® 8 Enterprise or Windows
Server® 2012 domain
http://technet.microsoft.com/en-us/library/hh852635.aspx#SideloadingRequirements
o By Activation Key
If not in domain the use volume license key.
o If not in domain and no activation key then
use AppStore. 

15. WP 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

16. The dream or reality?

17. 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.

18. Demo
Windows Phone 8
Hello World

19. Emulator
• Hardware-assisted virtualization supported and
enabled in the BIOS
• Second Level Address Translation (SLAT)
supported by the BIOS
• Hardware-based Data Execution Prevention
(DEP) supported and enabled in the BIOS

28. Your Apps Your way

29. Supported Languages

30. Project Templates
o C# (XAML)
o XNA
o C++
o HTML5

31. Demo
Windows Phone 8
JavaScript
Web App
jQuery
on Phone
http://wpwidgetlibrary.codeplex.com/

32. 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 

33. 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

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

35. Network Improvements
o Socket Listeners (Incoming)

o IPv6
o Winsock Support
o Proximity API
