Looking in Process Explorer it uses; Virtual Size: 550,000k , Working Set: 28000k

Why does my simple hello world console app use so much memory?

I take it the difference between the Working Set and Virtual Size means that difference will be paged to disk?

/I am running 64 bit XP.

Thanks

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Hello world");
        Console.ReadLine();
    }
}
