See http://forums.netduino.com/index.php?/topic/6799-https-support-on-n2/

The Netduino's .NET does not support SSL.
So we cannot send requests to Twilio!
So what we do is: create a small Node.js server and all it does is receive the request in HTTP and then creates a Twilio request to HTTPS (SSL)

My attempted Twilio code:

using System;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
using System.Text;

namespace AuthNet
{
    public class Program
    {
        public static void Main()
        {
            // write your code here
            var Interface = Microsoft.SPOT.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()[0];
            Interface.EnableDynamicDns();
            Interface.EnableDhcp();
            Debug.Print("IPAddress: " + Interface.IPAddress);
            foreach (var d in Interface.DnsAddresses)
                Debug.Print("DNS: " + d);

            Debug.Print("Started");

            string _Host = "api.twilio.com";
            var Entry = Dns.GetHostEntry(_Host);
            var _Address = new IPAddress(Entry.AddressList[0].GetAddressBytes());
            var _Port = 443;

            var accountSid = "";
            var authToken = "";

            var s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            IPHostEntry ipHostInfo = Dns.GetHostEntry(_Host);
            IPAddress ipAddress = ipHostInfo.AddressList[0];
            IPEndPoint endPoint = new IPEndPoint(ipAddress, _Port);
            //var EndPoint = new IPEndPoint(_Address, 80);
            s.Connect(endPoint);

            var url = "http://api.twilio.com/2010-04-01/Accounts/" + accountSid + "/SMS/Messages.json";
            //var text = KeyPadIndexToChar[(int)KeyCode].ToString();
            //string text = "\"" + _ID.Substring(0, 2) + " " + _Result + "\""; // +Result;
            string body = "From=+12356&To=+12323432&Body=testing";

            var databuilder = new StringBuilder();
            databuilder.AppendLine("POST " + url + " HTTP/1.1");
            databuilder.AppendLine("Accept: application/json");
            databuilder.AppendLine("Content-Type: application/x-www-form-urlencoded; charset=utf-8");
            //databuilder.AppendLine("Content-Type: text/plain; charset=utf-8");
            databuilder.AppendLine("Host: " + _Host);
            databuilder.AppendLine("Content-Length: " + body.Length);
            string credentials = Convert.ToBase64String(Encoding.UTF8.GetBytes(accountSid + ":" + authToken));
            databuilder.AppendLine("Authorization: Basic " + credentials);
            databuilder.AppendLine("Connection: Keep-Alive");
            databuilder.AppendLine("");
            databuilder.AppendLine(body);

            var databytes = Encoding.UTF8.GetBytes(databuilder.ToString());

            System.Net.Security

            Debug.Print("Sending...");
            var numbytessend = s.Send(databytes);
            Debug.Print("Sent");

            var buff = new byte[10000];
            var numbytesread = s.Receive(buff, 0, 10000, SocketFlags.None);
            if (numbytesread > 0)
            {
                var chars = Encoding.UTF8.GetChars(buff, 0, numbytesread);
                Debug.Print("Result: " + new String(chars));
            }


            var LED = new OutputPort(Pins.ONBOARD_LED, false);

            while (true)
            {
                LED.Write(true);
                Thread.Sleep(200);

                Thread.Sleep(100);
            }
        }

    }
