Suggested Answer: Explanation 🗳️
F: Example: Add an app service extension to package.appxmanifest
In the AppServiceProvider project's Package.appxmanifest file, add the following AppService extension to the <Application> element. This example advertises the com.Microsoft.Inventory service and is what identifies this app as an app service provider. The actual service will be implemented as a background task. The app service app exposes the service to other apps

B: Create the app service -
An app service is implemented as a background task. This enables a foreground application to invoke an app service in another application to perform tasks behind the scenes. Add a new Windows Runtime Component project to the solution.
C: Deploy the service app and get the package family name
The app service provider app must be deployed before you can call it from a client. You will also need the package family name of the app service app in order to call it.
