How do I prevent the app from terminating when I close the startup form?

How can i stop the application from ending when the main form is closed? I want to check if the Application.OpenForms.Count == 1 and only then close the application if its true. So I want to close the app when the last of the forms is closed.

Don't close the main form - hide it. – Oded Jan 21 '13 at 19:48

Pass an `ApplicationContext` to `Application.Run` and control app lifetime that way – David Heffernan Jan 21 '13 at 19:50
I'll still prefer Oded's answer.. simple to implement – Aniket Inge Jan 21 '13 at 19:50
@CofiPetrovic - Have you tried hiding the main form? Is this new development or modification of existing code? From the description, I'd say there's code smell. – P.Brian.Mackey Jan 21 '13 at 19:59
@Aniket It depends on the main form. If it's a large form with lots of content you can be holding onto a lot of memory needlessly by doing that, or leaking other resources that the form is holding onto such as file handles. – Servy Jan 21 '13 at 19:59
Sorry about the comment. – Cofi Petrovic Jan 21 '13 at 20:01
