As you already know, Aspose.Pdf.Kit for .NET has been merged into Aspose.Pdf for .NET and the former has been discontinued. I’m afraid, we do not sell Aspose.Pdf.Kit for .NET anymore. However, you can get the same functionality from the merged Aspose.Pdf for .NET.
The new merged version not only contains the new DOM API, but also provides the older API for backward compatibility. So, if you use Aspose.Pdf.Facades namespace of Aspose.Pdf for .NET, you’ll be able to execute your existing code as you would with separate Aspose.Pdf.Kit? If you need any guidance regarding the merged version then please have a look into this blog post.
We’re sorry for any inconvenience. If you find any further questions, please do let us know.
