Creating PDF files with C# .net 4.0

Question

Hi!
This is my first post, so please be gentle :)

I am looking for a C# library that can allow me to create PDF files from my database.
I found these two examples:
 
http://itextpdf.com/
and
http://www.pdfsharp.com/

does anyone have any other ideas or better alternatives? Does .net 4.0 have  any capability to create PDF files?

Thanks.
