Step Into (F11)

Question

If you use the Step Into in the following program. Yellow line is jump into the statement Console.WriteLine(base.GetType().Name); within the two curly brackets without going through private void k().

What is the reason for that? Problem is highlighted.

using System;

namespace contest
{
class Program
{
        static void Main(string[] args)
        {
                B b = new B();
                A a = new A();
                Console.Read();
        }
}
class A
{
        public A()
        {
                k();
        }
        private void k()
        {
                Console.WriteLine(base.GetType().Name);
        }
}
class B : A { }
}
