The caveat is that they used the 6-pin "ICSP" header for its digital communication--so you may need to solder the optional 2x3-pin header onto your Netduino. Not sure yet,

I had to lookup what the "ICSP" header is (its all new to me) and found that in one of your other postings that you explain that they duplicate existing pins, so maybe they are not required , If anyone has one of these shields, maybe they could tell us whether there is a socket under there in the middle which would match up with the ICSP header.
