The problem is actually that the dynamic type created returns System.MonoType
instead of the actual dynamic type.
Here is a simpler testcase narrowing the problem :


using System;
using System.Reflection;
using System.Reflection.Emit;

public class DynamicTypeTestcase
{
        public static void Main()
        {
                AssemblyName an = new AssemblyName();
                an.Name = "TestAssembly";

                AssemblyBuilder ab =
AppDomain.CurrentDomain.DefineDynamicAssembly(an,
AssemblyBuilderAccess.RunAndSave);

                ModuleBuilder mb = ab.DefineDynamicModule("TestModule",
"Test.dll");
                TypeBuilder tb = mb.DefineType("TestType",
TypeAttributes.Class);
                Type t = tb.CreateType();

                Console.WriteLine(t.GetType());//=> System.MonoType ...but
should be TestType
                Console.WriteLine(t.UnderlyingSystemType);//=> TestType ...but
should be System.MonoType ??
        }
}
