title: Using Dispose() to remove Control from Form
body: <p>Is it correct to use Dispose() to remove a Control from a Form?</p>
  
  <p>E.g. I have a button 'button1' on my formular. When calling Dispose() it    immediately disappears from the form and also from the 'Controls'-Collection of the form. But is this always the case? Or are there other cases (maybe other controls) where the GC waits some time?</p>
