            if (dlg.ShowDialog(win32Window) == System.Windows.Forms.DialogResult.OK)
            {
                result = Path.Combine(dlg.SelectedPath, resultFile);

}

A wrapper around the WindowsForms' FolderBrowserDialog - sets the defaults, allows for the initial location and sets whether the given path contains the filename as well.
