I am trying to upgrade an application that was build using MapObjects 2.0. It had GroupRenderer class but the class seems to be unavaliable for Arcobjects (.NET) for desktop development.
I don't remember the details of grouprenderer but you can look at ClassBreakRenderer, RepresentationRenderer, UniqueValueRenderer, etc.
MO 2.0 is more than 10 years old so perhaps you could describe what the class does (I assume renders a layer on the map) or what you need to accomplish.
