Remarks
Update the list of extensions that you are tracking when you handle this event to reflect the ones that have been unloaded. If the user re-installs the package, then a PackageInstalled event will be raised and you can re-add the extensions while handling that event just as you would the addition of any extension.
Like PackageUpdating, this event only passes the package that is being uninstalled and not a list of PackageExtensions.
