How to make the startup form initially invisible or hidden

My application has a System Tray and I don’t want the Window appearing on launch.

How can I accomplish this?

---

This is a default Windows Form application.

I dragged over a notifyIcon and a contexualMenuStrip

When the Form is closed, the application quits (don’t want that either). But when the application is launched, the Windows Form is also made visible. So how do I not launch the form on start up (and not quit on closing the window)?

Basically you need to overwrite SetVisibleCore() to achieve that… another option is to set ShowInTaskbar to false and use ApplicationContext in Application.Run.
