I am trying to figure out how to interface my NetDuinoPlus with the Seedstudio GPRS sheild?

I found this helper library here but when I add it to my project i keep getting errors about the namespace “serialPort” being missing or not found. I have added references to teh two required netduino helpers but there must be something else I am missing here. Does anyone have a good reference for making this shield with with NetDuino?

Thank you

well I made progress… I figured out you need to follow the links here to update to 4.2

I am now still getting errors in the helper library.

The type or namespace name ‘SMS’ could not be found (are you missing a using directive or an assembly reference?)

Any ideas are appreciated.
