Reduced testcase:

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

using System;

public class Tests
{
    public static long? foo (object o, long? bar) {
                Console.WriteLine (o);
        return 5;
    }

    public static int Main () {
        var del = (Func<long?,long?>)Delegate.CreateDelegate
(typeof(Func<long?,long?>), null, typeof (Tests).GetMethod ("foo"), true);

        var l = del (5);

        return 0;
    }
}
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

This is a bug in the 'closed over a null reference' feature, i.e. calling a
static method with its first argument set to null. No idea how this worked
before, it seems to fail with 2.6 too.
