Using PDFNet SDK in WPF Application

Q: Out application framework is WPF and I need a PDF viewer component
for WPF. I was looking at the PDFTron PDFNet SDK. Should I instead be
looking at the SilverDox SDK or does the PDFTron SDK include the
SilverDox?

For a concrete example, please see (save the file as ZIP).
