If you wanna use WPF styles in a Window Form app, its not possible but
you can use a WPF Host in your window form app and add your WPF user
controls in that and get more or less the view you are looking for...
Windows forms is not WPF and WPF is not
windows forms. You can NOT "style" a winforms application, at least, not
easily. You would have to use some kind of "skinning" library. In most
cases, your non-UI code from your winforms app can be used in the WPF
app. For example, a SOAP web service or WCF service.
You can, in some cases, put a WPF control in your windows form app,
and vice versa. it would be like taking your windows form app and
putting in ASP.NET. You are talking about 2 different platforms.
