Answer 1

You need to utilize systemd and Microsoft has a very detailed sample to guide you,

Answer 2

You can any console app with cron, or create a daemon process.

In Unix/Linux you create a daemon process, by disconnecting from the console. You do this by forking and redirecting stdout to a log file.

Fortunately ms has wrapped this up for with their service worker project type and UseSystemd(). See
