This is the code i'm using to achieve serial communication for a netduino plus 2 based on .NET micro framework. When i do i get a error message stating that "A using namespace directive can only be applied to namespaces; 'System.IO.Ports.SerialPort' is a type not a namespace ". Upon seeing this i comment out the line of code

using System.IO.Ports.SerialPort;

then I encounter couple of error messages stating that "'Microsoft.SPOT.Hardware.SerialPort.Configuration.Configuration(Microsoft.SPOT.Hardware.SerialPort.Serial, Microsoft.SPOT.Hardware.SerialPort.BaudRate, bool)' must declare a body because it is not marked abstract, extern, or partial"

Please help me resolve this issue as soon as possible. The scenario i'm working on is to get data from a barcode scanner via a rs232 cable connected to a breakout board which converts rs232 to serial. Thanks in advance.
