Morning everyone,
Maybe I'm missing something obvious here but I'm trying to open a SerialPort and when I execute the port.Open() command VisualStudio is asking me where the NetduinoHardwareProvider.cs file is. I have the SDK installed and I've only run into this (so far) when trying to use a SerialPort. Any thoughts? Below is the code & error text

using System;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
using System.IO.Ports;

namespace nd_serialTest
{
	public class Program
	{

		static InputPort btn = new InputPort(Pins.ONBOARD_SW1, false, Port.ResistorMode.Disabled);
		static OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);

		public static void Main()
		{
			SerialPort c1 = new SerialPort("COM1", 9600);

			Debug.Print("ready");

			if (!c1.IsOpen)
			{
				c1.Open();
				byte[] msg = System.Text.UTF8Encoding.UTF8.GetBytes("TEST");
				c1.Write(msg, 0, msg.Length);
				c1.Close();
			}
		}
	}
}
