An updated version of the CUPI .NET library and a new CUPI for Users .NET library can be found on their home pages here:

and

The CUPI library was updated with some items based on feedback from folks (thanks!) and the CUPI for Users library is what I used to build the iPhone Connection CoPilot application released on iTunes ¿ it¿s home page is here:

http://www.ciscounitytools.com/CodeSamples/Connection/CUPI/CUPI.html
both the home pages have links to the project source code and numerous training videos on how to get started using the libraries and using Mono for Android/iOS/Mac/Linux platforms etc¿ plenty of super-boring videos where you can point and laugh as I make lots of mistakes while writing demo applications.  Scripts are for cowards¿

Any and all feedback welcome as ever.
Enjoy.
