I have set a PDF profile PdfA_1B in the code, but the same is not reflected on the output.

prince = new Prince(myPrinceExePath, Events)
            {
                PdfProfile = PdfProfile.PdfA_1B,
                JavaScript = true,
                NoWarnCssUnknown = true
            };

Output generated has a version PDF/A-2B

I am using prince with .NET Framework 4.8 using NuGet package PrinceXMLWrapper by YesLogic Pty. Ltd.

what is wrong here ?

Could you upload the source files, and the resulting PDF file?

Could you try run Prince from the command-line, like this:

prince --pdf-profile="PDF/A-1b"  Input.html

Yes it is working in command-line, but we can't change to command-line as we are using nuget package everywhere and changing to command-line will require a lot of code changes.

@howcome: is there any problem with the nuget based prince wrapper ?

The attached Output.pdf file appears to have been modified by another program after being generated by Prince, do you have the original PDF file?
