We have introduced a merged version Aspose.Pdf for .NET 6.0.0. Could you please download and try it at your end? You can use the same code by including the namespace Aspose.Pdf.Facades, as it corresponds old Aspose.Pdf.Kit. If it still doesn’t resolve your issue then please share the input PDF files with us, so we could investigate the issue at our end and guide you accordingly.
We’re sorry for the inconvenience.
If your license is not expired then you can use either Aspose.Pdf for .NET or Aspose.Pdf.Kit for .NET license with the merged Aspose.Pdf for .NET. However, if the license is expired then you’ll have to renew the license to use the latest version. Nevertheless, you may get a temporary license for 30 days and try the latest version at your end.
I hope this helps. If you have any further questions, please do let us know.
