I see in this release notes of 16.2 of aspose.slides here http://www.aspose.com/docs/display/slidesnet/Aspose.Slides+for+.NET+16.2.0+Release+Notes
that UpdateSlideNumberFields propery has been removed but it doesn’t explain the new way to include slide numbers on presentations.
Can you please advise.
