>Ok, here we are with the request to generate a PDF from scratch, based on tables and fields, in our application. So, the client wants a clean good looking PDF report. Anyone has a good recommendation of a library that would be as simple as dropping a DLL in the Bin directory and obtain that namespace support from the .NET project?

The only one we've used is IText (http://itextpdf.com/) .
I didn't find anything that I needed (including graphics) that it could not do.
It's open source under AGPL licensing but you might have to buy a license for commercial use.....
