Just call Application.Run() and don’t pass anything. It belongs in your Main() method.

This keeps your main thread active and responsive to Windows notifications. Of course, there are not a lot of them since you don’t have a user interface anymore. Timers will work. A NotifyIcon will work. A hot key registered by pinvoking RegisterHotKey() will work. A low-level windows hook will work.

And SystemEvents will work. Which is important, you’ll need to subscribe its SessionEnding event to know when the user is logging off or shutting down Windows, you’ll need to terminate your app. Which you do by calling Application.ExitThread().
