Changing PDFnet SDK version from 6.1 to 6.6


I'd like to know what would it take to replace the dll (PDFNet.dll) from 6.1 to 6.6.


Assuming they are both the same .Net framework version (we offer a .Net 2 -3.5 and a .Net4+ version), and same architecture (32 or 64bit) then there should be nothing more than switching the assembly reference in Visual Studio.

The only dependency PDFNet.dll has is the Microsoft Visual Studio C++ Runtime redistributables. See the Getting Started document included in the SDK for links.

As for the API I’m not aware of any breaking changes.

Are you running into some sort of error? If so please post here.
