PDFsharp is a .NET library for processing PDF files. You create PDF pages using drawing routines known from GDI+. Almost anything that can be done with GDI+ will also work with PDFsharp.
Only basic text layout is supported by PDFsharp, and page breaks are not created automatically. The same drawing routines can be used for screen, PDF, or meta files.
This is free and open source software.
