PDF4NET is a .NET library for adding PDF capabilities in your .NET applications. Its simple and easy to use object model allows creating complex PDF documents or import existing PDF files with a few lines of code. Written entirely in C#, it is a 100% .NET component, not just a COM wrapper. And not to forget, ROYALTY FREE distribution.

PDF4NET 10 is the next generation of our well known PDF library PDF4NET. For the past 2 years we worked hard to bring PDF4NET up to date to latest technologies. This new release brings support for all .NET platforms, a fully rewritten internal architecture making it more testable and several new features that we could not support with the old version.

All these updates brought several breaking changes in the public API when compared to PDF4NET v5 but we're fully supporting the customers that wish the make the transition to the new PDF4NET.

Now, it seems to work perfectly. Thanks for noticing the missing blank line. Quick support can sometimes be crucial, and you certainly have a high service level!
