VS2008 & MM.NET 2008

I'm trying to use the CreateEntityList() found in the documentation:

Public Function GetCategoriesEntityList() As List(Of CategoriesEntity)

    Dim DataReader As IDataReader = Me.ExecSprocReader("CategoriesSelect")

    Return Me.CreateEntityList(Of CategoriesEntity)(DataReader)

End Function

I get the error that mmbindinglist can't be converted to generic.list.

Bug or Operator Error?

Thanks,
-Sid.
