    private abstract class Base<TResult> {
        private readonly System.Func<TResult> func = null;

        protected Base(System.Func<TResult> func) {
            this.func = func;

        }
    }

    private class Derived : Base<bool> {
        public Derived(bool myValue) : base(delegate() { return this.MyValue(); }) {
            this.myValue = myValue;
        }

        private bool myValue = false;
        private bool MyValue() {
            return this.myValue; // The "this" pointer is null here...
        }
    }

    Derived d = new Derived(true);
    bool result = d.Execute(); // This results …
