Hello, I am running mono under MacOSX Snow Leopard.

marco-cecconis-macbook-pro:Debug marcocecconi$ cat ../../Main.cs
using System;

namespace Primes
    class MainClass
        public static void Main (string[] args)
            const ulong max = 1000;

            bool[] numbers = new bool[max];

            for (ulong i = 0; i<max; i++)
                numbers[i] = true;

            for (ulong j = 1; j<max; j++)
                for (ulong k = (j+1)*2; k<max; k+=j+1)
                    numbers[k] = false;

            for (ulong i = 0; i<max; i++)
                if (numbers[i])
