So I am new the NetDuino and just purchased a N+2 and was told after my first post (where I was having trouble getting started) to search the forums for solutions and read the MS MF help files.
This tread, among many other on this forum, proves that SL is very lacking in support for their new products. I wonder if if is because they are deep into development to production of the Agent Watch, which looks very cool BTW. However, prototype boards like the NetDuino (and Arduino), in my opinion, are to allow us developers/engineers to build/create solutions/products, not go deep driving into framework source code to figure out why it does work. As much as I would rather do my work in C# and VS, my may have to return to C/C++ with Arduino to continue working on my modbus project and get my $70 back for the N+2.
So back to the topic... I tried all the suggestions above and I cannot get a file to actually be saved on the N+2 either.
Frustrated.
