Reflection Emit - C# - Indexer problem

Through Reflection Emit, a Type / class with an indexer (signature: string this[int]) is created this way:

DefineProperty - "Item" (System.Reflection.PropertyAttributes.SpecialName)
DefineMethod - getItem - "get_Item" (MethodAttributes.Public | MethodAttributes.HideBySig | MethodAttributes.SpecialName)
DefineMethod - setItem - "set_Item" (MethodAttributes.Public | MethodAttributes.HideBySig | MethodAttributes.SpecialName)
propertyBuilder.SetGetMethod(getItem);
propertyBuilder.SetSetMethod(setItem); 

The indexer can be invoked through Reflection, based on "Item" property:

object oIndexer = t.InvokeMember("Item",
 BindingFlags.Public | BindingFlags.GetProperty | BindingFlags.DeclaredOnly | BindingFlags.Instance,
 null, oInstance, new object[] { 0 });

From the code below, it finds indexer "Item" as well:

//type is the Type that was created through Reflection Emit
foreach (PropertyInfo property in type.GetProperties(
    BindingFlags.Instance | BindingFlags.Public))
{
    if (property.GetIndexParameters().Length > 0)
    {
        Console.WriteLine("Found indexer for {0} - {1}",
         type, property.Name);
    }
}

Weird thing is that in VS2005 intellisense, "get_Item" / "set_Item" methods are visible and can be invoked with correct result; while "Item" properyt is not visible.

Now the problem, when the Assembly generated through Reflection Emit is referenced and used, I cannot use this syntax - "this[int]' to access to indexer. Compiler Error: Cannot apply indexing with [] to an expression of type 'MyType'.

After much research and reading with no luck. I know I must be missing something simple. Any clues are greatly appreciated!

Got the answer from MSDN Forum...

//additional code for Indexer to work
ConstructorInfo ciDefaultMemberAttribute
    = typeof(DefaultMemberAttribute).GetConstructor(new Type[] { typeof(string) });
CustomAttributeBuilder abDefaultMemberAttribute
    = new CustomAttributeBuilder(ciDefaultMemberAttribute, new object[] { sIndexerName });//sIndexerName = "Item"
typeBuilder.SetCustomAttribute(abDefaultMemberAttribute);
