Hi ,

I have a C# Class which is inheriting from SortedDictionary. So when i do a automap , The properties like Count,items are getting created in the index mapping. Please help me to avoid these base class properties . I have already tried InferMappingFor , but this is not working. If anyone share the working code that would be really helpful and appreciated .
