title: How to create a non rectangular window form in c#?
body: <p>Is there any way of creating a non rectangular window form, such as circle or ellipse, in c# or .net?
  <br> I saw these unique windows form shapes and they look really neat in several installations I've seen.</p>
  
  <p>Also, is there any disadvantage in using this kind of design for non standard forms, such as sustainability, crashes, etc.?</p>
