Remarks
The event arguments contain a list of extensions within the extension package. Extensions are scoped by the <uap17:PackageExtension Name=...> defined in the extension's Package.appxmanifest file. Only extensions that match the <uap17:PackageExtension Name=...> defined in the host's Package.appxmanifest file are in the list.
The updated package may include new PackageExtensions, and may no longer contain PackageExtensions that were there previously. If you are maintaining a list of loaded extensions, the handler for this event is a good place to compare the list of PackageExtensions in the new package against your list and then update your list accordingly.
PackageExtension properties may have changed during the update. If you cached any of them, this is a good time to check for updates.
Generally the best way to handle this event is to treat it as you do the PackageInstalled event, but update your tracking list of PackageExtensions instead of creating a new tracking list.
