Hello, I'm trying to create a class library to monitor a netduino digital inputs and throw an event (not a native one but one I've created) everytime a DI passes from Low to High state. In my opinion it would be quite simple but for some reason when I try call the class in a WinForm app I've created in a new solution I get the security exception "ECall methods must be packaged into a system module." Any ideas? Thanks in advance.

Hi F4r14 and welcome to the Netduino boards! If I read this correctly you want a windows app controlling the Netduino-pins? That will be difficult; the Netduino runs code on it's own board without computer. So you deploy an application to the Netduino and will be executed there, not on the PC. You could create a link, with a serial port for example, but then you need to code both a windows app and a netduino app.

Thank you for your quick reply. Yes, that was what i inteded. For some reason i got the idea i could access the pins state through USB using the code shown in the examples.
If i was using Netduino plus would i be able to send the data through TCP/IP? The methods used to program TCP/IP communication in Netduino are the System.Net.Sockets?

Yes you could open a socket over TCP/IP and send data in both ways.
With a normal Netduino you could use a serial connection (can also be USB!) but it won't be using the Netduino API on the Windows PC; you should write your own transfer protocol and communicate from the PC to the app inside the netduino.

Just found an example using a "FTDI Basic breakout 3.3V". If i got it right it uses a Serial Port Emulator (PC) to receive the data sent from Netduino. It's a regular USB cable, right? So I would need a Netduino, the FTDI BB 3.3, USB cable, VCP driver and some lines of code for Netduino and PC app. Am I missing something?

You are quite correct. The break-out offers a serial-to-mini-USB connector:
