In this tiny program I address a Disposed() Form object. I expect an
exeption but don't get one. What is the status of a Disposed() Control?

using System;
using System.Windows.Forms;
class Class
{
 static void Main()
 {
  Form form=new Form();
  form.Text="Make a jazz noise here";
  Console.WriteLine("form status = {0}",form);
  form.Dispose();
  Console.WriteLine("form status = {0}",form);
 }
}

Output:

form status = System.Windows.Forms.Form, Text: Make a jazz noise here
form status = System.Windows.Forms.Form, Text: Make a jazz noise here

Disposing a form only frees up unmanaged memory; it does not de-reference
the class.
