What is the best practice to call server API with intervals in MAUI?

[jzhao8402]

I'm working on a MAUI project for Android, maybe iOS later, that requires the app periodically connecting to server API to synchronize data. I'm thinking to do one of the following.

1. use a background service - always running service; no need service side implementation
2. use push notifications (firebase cloud messaging) to inform the mobile about the server change; this requires server side implementation as well as mobile side
3. use a foreground service - when app is in running foreground;
4. use a timer - when app is in running foreground

This kind of user scenarios are quite common in mobile app design and I do understand these may require platform specific code. However, I just could not find any useful MAUI document or example of how to implement the background/foreground service, push notifications or even the timer. It looks like there is no out-of-box framework/support in MAUI for such simple needs.

Can anyone share advices on the best practice in MAUI for calling server API with given interval? Any useful MAUI example will be appreciated.
