Repro that doesn't depend on the DLR implementation:


using System;
using System.Reflection.Emit;

class Program {

    static void Main ()
        var method = new DynamicMethod ("test", typeof (int), new [] { typeof
(Program) }, true);
        var il = method.GetILGenerator ();
        il.Emit (OpCodes.Ldc_I4, 42);
        il.Emit (OpCodes.Ret);

        var @delegate = method.CreateDelegate (typeof (Func<int>), null);
        Console.WriteLine (@delegate.DynamicInvoke ());
