Hi Chris;
Yes, my framework has various flavours - they are: EAServer, PocketBuilder, IIs (web services), PB Classic (Win32, Winform, Webform), PB.Net (WPF), Appeon Web (since 2008) and now Appeon Mobile.
FYI: I am currently collapsing my PB Classic, Appeon Web and Appeon Mobile (including PocketBuilder) FC versions into one "Integrated" version. 
Question: Should I discontinue the PB.Net (WPF) flavour? Last month I had 2 downloads of the WPF version and 132 downloads of the PB/Appeon versions. To me - the PB.Net stuff seems to be dying off. Last year I would average 10-20 downloads a month of the WPF flavour whereas this year its dropped off to almost nil for PB.Net. 
Regards ... Chris
