Thanks to generics in 2.0, now any value type can be NULL.

    public class DateTimeNullTest
    {
        private Nullable<DateTime> oDate = new Nullable<DateTime>(DateTime.Now);

        public DateTimeNullTest()
        {
            // Yay - It doesn't blow up!
            if (oDate != null)
                oDate = null;
        }
    }
