Yes, targeting the 4.2 framework does get me up and running. Strange thing, code that used to work fine, now gives me an exception. It's the first call in my listener that is now causing the trouble. I have this call:
using( Socket clientSocket = listeningSocket.Accept() )
and that is what is triggering the exception.
Couple of things. If I want to get current on Netduino hardware, what would you suggest? And, are there any examples of simple web servers working on the experimental framework?
Thanks for the help, very much fun getting back into this after a few years!
