FreeSpire.PDF attachment

[angelo.celoni]

Hi Spire Support,
I'm working on a project that involves extracting an XML attachment from a PDF file and I tested your FreeSpire.PDF product version 5.10.0 installed via NuGet.

I get the error:
'pdf.Attachments' threw an exception of type 'System.NullReferenceException'
The stacktrace is as follows:
    in Spire.Pdf.Attachments.PdfAttachmentCollection..ctor (spr ᝛ A_0, spr ៝ A_1)
    in spr ⠇. ᜉ ()
    in Spire.Pdf.PdfDocument.get_Attachments ()

Using Spire.PDF version 5.11.2 installed via NuGet the error does not occur.

Is there a FreeSpire.Net update that solves the problem?

Thank you,

Angelo
