I had a need to view PDF files directly within a WPF application and Stackoverflow and Google did not provide much assistance, so I set out on my own to see what I could create. It turns out, it is not that difficult. The trick is to use the WinForms support in WPF ala the WindowsFormHost control. The application is so simple, I built it start to finish in under 5 minutes and captured it in a screencast for you to check out.
