c# script waiting in terminal but exiting directly as a daemon

- i am a complete c# noob (i know Java though) - i have a c# script i modified. I want to run it at startup using a daemon and systemctl (the original is this NZXT automatic fan controller script ) - the code created a repeating timer to execute a piece of code every 4 seconds and blocks exiting the script using Console.ReadLine(); - i compiled and tested the script using msc and mono. it works as intended in a terminal (it is NOT exiting directly) - when run as a daemon, Console.ReadLine(); doesn't wait and the script directly completes the main method and exits - NOTES: - - i am also a linux moob, so please point out if i am doing something wrong in the daemon. My goal is having a background script that i can start and stop, which the system starts from me on boot - please find all code attached below main code:
