Designed for .NET / ASP / VB
Until version 6, there were two products - ABCpdf ASP and ABCpdf .NET. Although functionally similar, architecturally they were fundamentally different. At version 7 ABCpdf ASP was discontinued and in its place an identical COM interface was layered over ABCpdf .NET to provide backward compatibility with ABCpdf ASP.
