Why have a main form at all?
I've never really understood why so many people go to such lengths to have a
hidden main form and try to keep it invisible, rather than going for the
much simpler expedient of not using a main form at all.
Windows Forms doesn't require you to have a main form. If you just start
the app up like this:
Application.Run();
i.e. you don't pass in a form, then there is no main form. This means you
don't need to worry about it appearing in the Alt-Tab list - something
that's not there isn't going to appear!
So all you need to do is make sure you add the notify icon to the
notification area before you call Application.Run.
You'll also need to work out how you're going to shut down. If you don't
have a main form, the application will run until you call Application.Exit.
