How to Exit a FORM automatically?

Question

I created a VB project of the type Console App (.Net Framework). The objective of the below code is to make a FORM appear and then immediately disappear. However although the form is appearing correctly it is not closing by itself. Can anyone pls help pointing out my mistake? I tried to see how the control moves by setting up a break point and found that after executing the statement Application.Run(New Form1) (i.e. after launching the form) the control does not move to the next statement Application.Exit() by itself. Only when I manually close the FORM (by clicking on x icon) do I find the control moving to the Application.Exit() statement. But then I have already closed the form manually so does this statement at all do anything? If not, then how to modify the code to make the FORM automatically close after being visible.

Imports System.Windows.Forms

Public Class Form1
    Inherits Form    'System.Windows.Forms.Form

End Class
Module Module1
    Sub Main() 'launches the console window

        Application.Run(New Form1) 'Opens a new Form
        Application.Exit(0)   'Supposed to close the form that was opened but not closing
    End Sub  'closes the console window

End Module

Also, please note I am deliberately not creating a WPF application as I want to understand how the classes/commands under the System.Windows.Forms namespace work.

Try something like this:

Dim f As New Form1
AddHandler f.Shown, Sub()
                        Thread.Sleep (1111)
                        f.Close()
                    End Sub
Application.Run(f)

Sleep was added to show the form for short period; you can remove it.
