4. Introduction
Universal Windows Platform (UWP)

5. One Windows Platform
Windows 8.1 and Windows Phone 8.1
apps target an operating system
With Windows 10 apps targets one or
more device families
The set of APIs in the universal device
family is inherited by child device
families.

6. Easy for users to get
& stay current
Unified core
and app platform
The Convergence Journey
Windows 10
Converged
OS kernel
Converged
app model

7. Windows 10 Editions Announced
Windows 10 Home
Windows 10 Mobile
Windows 10 Pro
Windows 10 Enterprise
Windows 10 Education
Windows 10 Mobile Enterprise

8. Visual Studio 2015 Product Editions
Enterprise
Professional
Community
*Blend for Microsoft Visual Studio

9. Developer Checklist

the Windows 10 SDK
Extras

Hyper-V (hardware dependent)
• Phone emulator

10. Supported Programming Languages

12. Device Families
With Windows 10 apps targets one or more device
families not the Operating System

13. Solution Layout
Is there a Appx Manifest?
Is there a Head project?
Is there a Shared project?
Are there #IF directives?

14. Demo
UWP Apps

15. Extension SDKs

16. Shared Projects
Windows
Binary Phone
Binary

17. Not all APIs were available everywhere

18. Compilation Directives
C# Syntax
#if WINDOWS_PHONE_APP
Windows.Phone.UI.Input.HardwareButtons
.BackPressed += this.HardwareButtons_BackPressed;
#endif
C++ Syntax
#if WINAPI_FAMILY==WINAPI_FAMILY_PHONE_APP
_backPressedEventToken = HardwareButtons
::BackPressed += ref new EventHandler
<BackPressedEventArgs^> (this,
&NavigationHelper::HardwareButton_BackPressed);
#endif

19. Introducing Platform Extension SDKs
• Extends the UWP
• Targets specific platforms
• Updates at a separate cadence
• Enabled on every device

20. Adding Extensions

21. Testing for capabilities
IsApiContractPresent
IsEnumNamedValuePresent
IsEventPresent
IsMethodPresent
IsPropertyPresent
IsReadOnlyPropertyPresent
IsTypePresent
IsWriteablePropertyPresent
Windows.Foundation.Metadata.ApiInformation

22. Test capabilities at runtime
var ns = "Windows.Phone.UI.Input.HardwareButtons";
if (Windows.Foundation.Metadata.ApiInformation.IsTypePresent(ns))
{
Windows.Phone.UI.Input.HardwareButtons
.BackPressed += Back_BackPressed;
}

23. What about shared projects?
Still completely supported
Compilation directives are supported, too
1. WINDOWS_APP
2. WINDOWS_PHONE_APP
3. WINDOWS_UAP (new)
You still need to test for API support

24. New XAML Controls
SplitView, RelativePanel,
MonthCalendar

25. Navigation Framework
The Frame
• Frame.Back/FrontStack
• CanGoBack()
• GoBack()
• CanGoForward()
• GoForward()
• Frame.Navigate(Type, Parameter)
• Navigating event
• Navigated event
• Frame.Get/SetNavigationState()
Frame
PageBackStack FrontStack

26. The Page
• Key overrides
• OnNavigatedTo(parameter)
• OnNavigatedFrom()
• Page.NavigationCacheMode
• Enabled (based on Frame’s CacheSize limit)
• Required (always, no limit)
• Disabled (never)
Navigation Framework

27. SplitView

28. Common behaviour, custom design
Your Windows App

29. SplitView.Pane
<SplitView>
<SplitView.Pane>
<StackPanel>
<RadioButton />
<RadioButton />
</StackPanel>
</SplitView.Pane>
</SplitView>

30. SplitView.Content
Splitview.Content is intended to be the Frame
<SplitView>
<SplitView.Pane />
<SplitView.Content>
<Frame/>
