Interesting OOPS puzzle [closed]

Assuming you meant B A C on three lines (plus no typo on main method name):

namespace ConsoleApplication1
{
    public class BaseHome
    {
        static BaseHome()
        {
            Console.WriteLine("B");

            AppDomain.CurrentDomain.ProcessExit += new EventHandler(OnProcessExit);
        }

        public static void Main()
        {
            Console.WriteLine("A");
        }

        private static void OnProcessExit(object sender, EventArgs e)
        {
            Console.WriteLine("C");
            Console.Read();
        }
    }
}
