Hi Martin,
Thank you for your interest in Syncfusion products.
Please refer the below assemblies to run the PDF application.
Syncfusion.Core
Syncfusion.Compression.Base
Syncfusion.Pdf.Base
Also, with the latest version we don't have support for 4.4 versions PDF, we have marked it as Pdf.legacy and we are not providing any fixes or features in the legacy version. We strongly recommend you to upgrade to our latest version Volume1, 2009 and this is only actively supported and improved.
Please download the latest version from the below forum thread.
