2. The monolithic app This app does it all Impressive, isn’t it!
But just try changing it 

4. Why build a family of co-operating apps?
Don’t reinvent the wheel
There are apps out there that are amazing at what they do – extensibility helps you leverage them.
Better Together
Extensibility makes it easy to plug in existing services that your users rely on every day
Adding functionality
Have you ever used an app and thought of a great feature? Extensibility lets you make it happen.
Reduce development and maintenance costs
Decomposing complex systems into discrete components with clear functionality, and with simple interfaces to other apps can lead to reduced software development and maintenance costs.

What are we going to do?
Leverage other apps to perform image manipulation

14. App Handover with Protocol Associations

16. Discovery Verify protocol is supported on device
var queryUri = new Uri("appb-forresults:");
string packageFamilyName = "sample.uwpappb";
await Launcher.QueryUriSupportAsync(queryUri,
LaunchQuerySupportType.Uri, packageFamilyName);

17. Usage UWP App A UWP App B var options = new LauncherOptions();
options.TargetApplicationPackageFamilyName = "sample.uwpappb";
await Launcher.LaunchUriForResultsAsync(new Uri("appb-forresults:?works=today"), options);
UWP App A
UWP App B
var resultData = new ValueSet();
resultData.Add("Result", "Value");
operation.ProtocolForResultsOperation.ReportCompleted(resultData);

18. Why LaunchUriForResultsAsync?
Lightweight App Handover
Reuse instead of Rebuild
Cross-Promotion

21. App Services Store apps can provide services to other Store apps

22. Discover Query For Support
var services = await AppServiceCatalog. FindAppServiceProvidersAsync("com.my.appservice");

23. Create Add a background service Declare App Service In Manifest
<uap:Extension Category="windows.appService"
EntryPoint="BackgroundService.Service">
<uap:AppService Name="com.my.appservice"/>
</uap:Extension>
Add a background service
//Regular Service Background task
public sealed class Service : IBackgroundTask

24. Usage Connecting to an App Service Messaging via App Services
using (var connection = new AppServiceConnection()) {
connection.AppServiceName = "com.my.appservice";
connection.PackageFamilyName = "my.app";
AppServiceConnectionStatus status = await connection.OpenAsync(); … }
Messaging via App Services
var request = new ValueSet();
request.Add("key", "value");
var response = await connection.SendMessageAsync(request);

25. Why App Services? Background Execution App to App Messaging
Stay within the context of the invoking app
App to App Messaging
Available across devices - Project Rome

26. App Service Lifetime
Service is activated on-demand, and persist for the length of the connection
Client may terminate service by disposing its AppServiceConnection
If the invoking app is suspended, app services sponsored by the app will be terminated
Insufficient resources may cause launch failure or service termination

27. App Extensions

28. Host Package.appxmanifest
<uap3:Extension Category="windows.appExtensionHost">
<uap3:AppExtensionHost>
<uap3:Name>PhotoExt</uap3:Name>
</uap3:AppExtensionHost>
</uap3:Extension>

29. Extension Package.appxmanifest
<uap3:Extension Category="windows.appExtension">
<uap3:AppExtension Name="PhotoExt"
Id="base"
PublicFolder="Public"
DisplayName="Invert"
Description="Invert Image">
</uap3:AppExtension>
</uap3:Extension>

31. AppExtensions API Summary
using Windows.ApplicationModel.AppExtensions;
Open Extension Catalog
var catalog = AppExtensionCatalog.Open("PhotoExt");
Find Extensions
IReadOnlyList<AppExtension> extensions = await catalog.FindAllAsync();
Get Notified
catalog.PackageInstalled += Catalog_PackageInstalled;
Load Content
StorageFolder folder = await ext.GetPublicFolderAsync();

32. App Extensions Host and Extension both opt-in via declaration
Host provides the dev platform
App Extensions are apps!

43. App to App Extensibility
Use Protocol Associations for lightweight App Handover and reuse rather than rebuild
Use App Services for background message passing and make apps work better together
Use App Extensions, which offer great discovery and management, to connect and share content
Use Protocol Associations and App Services to connect and share content across devices

44. App to App Extensibility
Use all these techniques together to build an ecosystem
