This document provides an overview and agenda for developing Windows 10 apps, covering topics like the new Windows Core platform, universal app platform (UAP) and versioning, new controls like the Relative Panel and Month Calendar, enhanced app-to-app communication features, and the Action Center for managing notifications. It demonstrates new APIs for capabilities detection, extension SDKs, URI activation, launching apps for results, app services, and handling Action Center triggers from a background task.

1. Develop for Windows 10

3. Agenda
Windows Core
New Controls
App-to-App Communications
Action Center

4. First, Windows Core
One, Common source
One Windows kernel
One File I/O stack
One app model
More…

5. Easy for users to get
& stay current
Unified core
and app platform
The convergence journey
Windows 10
Converged
OS kernel

app model

6. UAP = Universal App Platform
A collection of contracts & versions

7. Target a version of UAP
not the Operating System

8. Platform Versioning
<TargetPlatform
Name="Microsoft.Universal"
minVersion="2.0.0.0"
maxVersionTested="3.5.0.0" />

9. Safely deploy one binary
to every type of device

10. Extension SDKs
UAP
Windows Core Windows Core Windows Core Windows Core
UAP UAP UAP
Desktop Mobile Xbox More…

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

12. 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;
}

13. Platform extensions
<ItemGroup>
<!-- Reference to the .Net Framework
and Windows SDK are automatic -->
<SDKReference Include="Windows Desktop,
Version=10.0.9910.0"/>
<SDKReference Include="Windows Mobile,
Version=10.0.0.1"/>
</ItemGroup>

14. DEMO
Visual Studio
3:33

15. New Controls

16. Relative Panel
Adaptive
Relative to the panel
Relative to a sibling
Simplified XAML
Simplified Visual Tree
Simplified Visual State

17. Month Calendar
Basic operation
Date picker
Calendar view
Density bars
Investment
Outlook calendar
System calendar

18. SplitView

19. SplitView.PaneDisplayMode
SplitView.IsPaneOpen
"True"
SplitView.IsPaneOpen
"False"
Inline
Overlay
Compact Inline
Compact Overlay

20. Visual State setters & triggers
Setters set discrete properties
Many properties do not need animation
Triggers declare when a state is applied
No need to manually handle events in code-behind
<VisualState x:Name="wideState">
<VisualState.Setters>
<Setter Target="myPanel.Orientation" Value="Horizontal" />
</VisualState.Setters>
<VisualState.StateTriggers>
<AdaptiveTrigger MinWindowWidth="600"/>
</VisualState.StateTriggers>
</VisualState>

21. App to App Communication
enhancements in Windows 10

22. Enhanced App to App in Windows 10
Send file token, send data
Launch a *specific* app
App Services
Launch for Results

23. URI Activation++
Invoke a specific app
var options = new LauncherOptions();
options.TargetApplicationPackageFamilyName = "24919.InstapaperIt";
var launchUri = new Uri("instapaper:?AddUrl=http%3A%2F%2Fbing.com");
await Launcher.LaunchUriAsync(launchUri, options);

24. URI Activation++
Send Files
var options = new LauncherOptions();
options.TargetApplicationPackageFamilyName = "24919.InstapaperIt";
var token = SharedStorageAccessManager.AddFile (gpxFile);
ValueSet inputData = new ValueSet();
inputData.Add("Token", token);
var launchUri = new Uri("instapaper:?AddUrl=http%3A%2F%2Fbing.com");
await Launcher.LaunchUriAsync(launchUri, options, inputData);

25. Query URI Support
Discover if app already installed to handle a Uri
var queryUri = new Uri("instapaper:");
await Launcher.QueryUriSupportAsync(queryUri, LaunchUriType.LaunchUri);
?
var queryUri = new Uri("instapaper:");
string packageFamilyName = "24919.InstapaperIt";
await Launcher.QueryUriSupportAsync(queryUri, LaunchUriType.LaunchUriForResults, packageFamilyName);

26. Launch for Results
Launching the app
var options = new LauncherOptions();
options.TargetApplicationPackageFamilyName = "24919.Instap";
var launchUri = new Uri("instapaper:?AddUrl=http%3A%2F%2Fbing.com");
await Launcher.LaunchUriForResultsAsync(launchUri, options, data);
var resultData = new ValueSet();
resultData.Add("Result", value);
operation.ProtocolForResultsOperation.ReportCompleted(resultData);A
App1 App2

27. App Services
Web Services on Device
Client App A
Client App B Background Task
App with App Service

28. Action Center
managing your notification space

29. Action center & Quick actions

30. Action Center – User Experience
20 Notifications per app
Persistent notifications for 7 days (or shorter)
Users can:
- “chase” (tap) a notification (removes it from the action center)
- remove a group of notifications
- remove all notifications
First available on Phone in 8.1 - now on Windows
10 desktop as well!

31. Action Center Management APIs
Manage app notifications
Developers can:
• Remove one or many notifications
• Tag and group notifications
• Replace a notification with a new one
• Set an expiration on notifications
• Send “Ghost Toast” notifications (only show up in the notification center)

32. Action Center change triggers
ToastNotificationHistoryChangedTrigger
• Fires whenever a user dismisses a notification from Action Center
• Or when an app adds or removes or replaces a notification
Use to trigger a Background task in which you can maintain
consistency of unactioned item counts in app state and on
Tiles

33. Action Center change trigger
// Background task for a ToastNotificationHistoryChangedTrigger
public sealed class ActionCenterChangedTask: IBackgroundTask
{
public void Run(IBackgroundTaskInstance taskInstance)
{
var toasts = ToastNotificationManager.History.GetHistory();
if (toasts != null)
{
var count = toasts.Count();
if (count== 0)
{
BadgeUpdateManager.CreateBadgeUpdaterForApplication().Clear();
}
else
{
XmlDocument badgeXml = BadgeUpdateManager.GetTemplateContent(BadgeTemplateType.BadgeNumber);
XmlElement badgeElement = (XmlElement)badgeXml.SelectSingleNode("/badge");
badgeElement.SetAttribute("value", count.ToString());
BadgeNotification badge = new BadgeNotification(badgeXml);
BadgeUpdateManager.CreateBadgeUpdaterForApplication().Update(badge);
}
}
}
}
