You might need to create an instance of the OpenFileDialog control, I'm not sure if you can do this... — Bali C, Jul 23 '12 at 13:12
Can you provide full code? and what you are trying to implement? — Anuraj, Jul 23 '12 at 13:12
I had a similar problem recently with my PC. Turn off Windows' Aero theme and try again. — Tharwen, Jul 23 '12 at 13:12
Use SysInternals' AutoRuns utility and disable shell extensions. — Hans Passant, Jul 23 '12 at 13:33

Another suggestion was disable the AutoUpgrade option or set it to false.

This would be the correct way:

OpenFileDialog of = new OpenFileDialog();
of.ShowDialog();

EDIT Additionally, this problem may occur in .NET Framework 2.0 Remoting applications on a computer that is running certain types of driver software or antivirus programs.

For testing, please close the antivirus.

It depends on how the OP has added the OpenFileDialog component. If the OP added the OpenFileDialog directly in code then this could be the answer, but if the OP used the designer to drag the OpenFileDialog component, then there is another reason for the crash. – Steve Jul 23 '12 at 13:21
