Abcpdf .Net version 8 works but it creates lot of issue in production servers where security and user rights are restrictive.
It is difficult to directly to do URL->pdf conversion. We ended up URL-Save HTML in local folder ->read HTML and convert to PDF-> delete HTML file from folder - tricky approach but it works. The only flaw is that you need to give read/write permission on a folder on server. Its still better than decreasing security settings.
