In VB.Net you can show a form without crete an object reference before... vb.net do it to you, but, that \"feature\" is generating many problems, eg:
Public Clas
No there is no way to disable that. It is called the default instance. If you don't want to use it - don't use it. I recommend creating a new instance.
Dim f3 As New Form3 f3.Show()
