The release of Windows 8 represents a bold entry into the world of tablet PCs by Microsoft. With Windows Store applications it is possible to write highly responsive, touch-friendly applications that run efficiently on multiple form factors including new ARM devices. The Microsoft team has taken great care to accommodate your existing knowledge by embracing both C# and the managed code stack and XAML technologies, but there are important fundamental differences. In this deep dive of the Windows 8 stack, Jeremy Likness covers the inner workings of the engine, reveals how it relates to traditional Silverlight and WPF development, and highlights the areas that are important for developers to understand as they transition from the Silverlight and WPF platform to Windows 8 with help from the Portable Class Library (PCL.)

5. Introduction: Windows 8 Apps
• Brand new look and feel
• Run on a variety of devices
• Sold through the Windows Store
• Language choice (we’ll focus on C#/XAML, but C++/XAML and
HTML5/JavaScript are available)
• Single, chromeless window that fills the entire screen
• Multiple layouts – orientation, snapped, form-factors, etc.
• Touch-first but pen, mouse, and keyboard friendly
• Apps “talk to each other” through contracts
• New controls and UI surfaces
• Tiles instead of icons

7. XAML and Blend
• XAML very similar to Silverlight/WPF
– Namespaces change
– No markup extensions
• Still design-time friendly
• MVVM built-in to the templates
• You still have a friend in Blend!

9. Animations
• Same old story(board)
• Plus a whole lot more
• Animations Library makes life easy

11. Styles
• Same concept, can use styles “as is” in
many cases
• Resource keys allow for theme-aware
styles (ex: high contrast)
• Same parts and states for controls
• StyleSelector to return styles

13. StyleSelector
public class MyStyleSelector: StyleSelector
{
protected override Style SelectStyleCore(
object item,
DependencyObject container)
{
Style style = new Style(typeof(ListViewItem));
style.Setters.Add(new Setter(
ListViewItem.ForegroundProperty,
new SolidColorBrush(Colors.Red)));
return style;
}
}
<ListView ItemsSource="{Binding Widgets}"
ItemContainerStyleSelector="{StaticResource MyStyleSelector}" />

14. New Controls
• Progress ring
• Spell-check support
• GridView
• ListView
• FlipView
• SemanticZoom
• Touch-first

16. Visual State Manager
• Behaves the same as Silverlight
• Used in the fundamental templates
• Helpful for orientation and display
mode changes
• Full Blend support

18. WinRT
• The new API for Windows 8 apps
• Has it’s own type system
• Provides language projections for support in JavaScript,
C#, C++, etc.
• Automatic mapping between types
• You can create WinRT using managed code for
consumption by non-managed Windows Store apps
• See the built-in WinRT types:
c:windowssystem32WinMetadata
• Uses ECMA-335 for type definitions – use ILDASM.exe

20. Charms, Contracts, Extensions
• Use Charms (Windows Key + C) to invoke certain contracts
• Contracts are agreements between Windows Store apps
• Extensions are agreements between Windows Store apps
and the Windows 8 operating system
• Contracts: Cached file updater, file picker, play to, search,
settings, share
• Extensions: account picture provider, AutoPlay,
background tasks, camera settings, contact picker, file
activation, game explorer, print task settings, protocol
activation, SSL/certificates

22. Application Bar
• Similar to Windows Phone concept
• Drop-in control
• Automatically handles show/hide
• Advanced scenarios like IE10
• Commands live at the edge:
– Right-edge = Charms and “system level” commands
– Bottom, top edges = Application commands

23. Portable Class Library
• Built into Visual Studio 2012
• Dozens of profiles based on various combinations
• Finds the common API surface area between target
platforms
• Supported targets:
– .NET Framework 4.0 – 4.5
– Silverlight 4 – 5
– Windows Phone 7 – 7.5
– .NET for Windows Store apps
– Xbox 360
• More targets = less surface area
consulting training design debugging wintellect.com
24. Strategies for Managing the Gap
• Only target the specific frameworks you know you will use
(i.e. don’t target Windows Phone if that’s not on your
radar)
• Build as much functionality into the API surface area you
can
• Use interfaces (IoC/DI) and delegates for functionality that
must be platform specific
• Don’t try to share XAML. The various targets all have
different design considerations.
