UART transmit sequence stopped

I was doing a short program to understand de UART transmission. For it, I am using COM2 Port connected to an FTDI basic allowing connection to a USB (Windows 10). I am using Hyperterminal to receive serial information.
This is the code I am using in Visual Studio 2015.

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

namespace UARTtrms
public class Program
static SerialPort transmitter = new SerialPort(“COM2”, 9600, Parity.None, 8, StopBits.One);

    public static void Main()
        int count = 0;
        string msg = count.ToString();
        while(count < 35)
            transmitter.Write(Encoding.UTF8.GetBytes(msg), 0, msg.Length);
            msg = (++count).ToString();


My question is: Why only two sequences of numbers are transmitted? In a logic way should be sent 35 sequences.
