For my C# WinForms project, I created a self-contained package and it works. Problem is that I use System.Windows.Forms.VisualStyles to have dialogs in Vista style, but the style is not applied, the routine I use to show the Vista dialog return error (in which case I make the routine use the default dialogs, so no prompt is shown to the final user).

What should I distribute to make it work?
I also already included a manifest and the Application.EnableVisualStyles() method at the beginning of the Main() method.

Note that the software works as expected if executed from Debug folder or from the IDE itself, but not from the Release folder after the self-contained package is created.

I expect the Vista style dialogs to be displayed to the user in place of the standard common dialogs.
