PDFsharp & MigraDoc Foundation

Hello,

I am using PdfSharp 1.50.5147 on a UWP app through NuGet. It works well for the most part.

But for some of the files that were produced on MacOS environment, when I call this PdfReader.Open(inStream, PdfDocumentOpenMode.Import); function, I'm getting the following error.
Invalid entry in XRef table, ID=8, Generation=0, Position=0, ID of referenced object=4, Generation of referenced object=0
at PdfSharp.Internal.ParserDiagnostics.ThrowParserException(String message)
at PdfSharp.Pdf.IO.Parser.ReadXRefTableAndTrailer(PdfCrossReferenceTable xrefTable)
at PdfSharp.Pdf.IO.Parser.ReadTrailer()
at PdfSharp.Pdf.IO.PdfReader.Open(Stream stream, String password, PdfDocumentOpenMode openmode, PdfPasswordProvider passwordProvider)

I can open these files on the Adobe tools and browsers and once saved with the Adobe tools, the above function starts to work with those files.

Looking forward to hearing from you

Thank you

The file is corrupted.
The strict check has been removed from newer versions of PDFsharp (I don't remember when).
So either get the latest version of PDFsharp or take the source code of PDFsharp 1.5 and comment that check out.
I don't know if version 1.51 still has that check.
