Background task invoked by raw push notification
Thank you for the suggestion. We are not adding this capability in the 8.0 release, but know that it is high on the consideration list for future Windows Phone releases.
Yes I definitively want to do that too : defining a callback executed when a (toast/tile/raw notification) is received by the app, this way I could prepare data, or update the tile in a more complex way than what is feasible now !
Raw Notifications are quite useless at the moment, as the app has to be running.
And e.g. Toast Notifications are stupid because you can't get (much) data to the actual app. So after clicking your toast, the app still has to refresh your data.
A background task which is invoked when a raw notification arrives. This task could then process the data, save it locally, and (maybe based on some conditions) display a toast notification.
That way everything would work much faster and more convenient.
