No matter how In write this program this is the error I get: System.IO.IOException: Read-only file system at System.I

Program.cs 
using System;

class Program
{

    static double Divide(int dividend, int divisor)
    {
        return ((double)dividend / (double)divisor); }

    static void Main(string[] args)
    {
        // This should print "2.5".
        Console.WriteLine(Divide(5, 2));
        // This should print "3.3333333333..."
        // (Or a value close to that, since it can't be
        // infinitely precise.)
        Console.WriteLine(Divide(10, 3));
    }

}

This code looks OK to me, plus the message about the "file system" makes me think there could be some problem with the server that performs the checking.
