It looks like the docs for the .net API for Aspose.PDF are missing on your site. When I pull up this link, I see links for ‘Product Information’, ‘Programmer’s Guide’, ‘Knowledge Base’ and 'Aspose.Pdf for Java API Reference ’ but it looks like the .net link is missing.
With the release of the new version of Aspose.Pdf, the online documentation was also updated. Unfortunately, it seems we skipped a link during that time. The issue has been noticed, and a request for correction has been forwarded. The link will soon be available.
Thanks for your notice and sharing the information. We apologize for your inconvenience.
