the following sample code works on windows but fails on mono. Note that this
worked about a month or so ago so something recently caused this error to now

using System;
using System.Collections;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Reflection;

  public interface IChildInterface


   public class ChildClass1 : IChildInterface


   public class TestGeneric<T>

      public void Set(T v, IChildInterface r)

      public void Set(T v)

      public void Set(T v, params long[] index)

      public void Set(T v, IChildInterface r, params long[] index)

   class monofail4
      static int Main(string[] args)
         Type genTypeProp =
         object propArray = Activator.CreateInstance(genTypeProp, new object[]
{ });
         Type[] arrTypes = new Type[2];
         arrTypes[0] = typeof(double);
         arrTypes[1] = typeof(ChildClass1);
         MethodInfo methPropArray = genTypeProp.GetMethod("Set", arrTypes);

         ChildClass1 a1 = new ChildClass1();
         object[] arrParameters = new object[2];
         arrParameters[0] = 15;
         arrParameters[1] = (IChildInterface)a1;
         methPropArray.Invoke(propArray, arrParameters);

         return 0;
