I have an attached glass sunroom. The room has "special" glass that doesn't get hot or really cold with the seasons, but the aluminum window frames really conduct both heat and cold making the room unusable without A/C or heat. I was thinking that the frames could be insulated with foam...anyone ever done this?

Not going to happen.
Older or less expensive aluminum framed windows have no thermal break between the inside and outside of the frames.
One of the joys of metal framed windows.
Google thermal break for some pictures.

Depends on the room and the foam will not improve the comfort of the extrustion that much either way.

Trapped air will have an R-value about 1 in that assembly. Adding insulation to the void space (if not thermally broken) will not improve it that much.

Most of the heat loss is via the structure if it isn't thermally broken.

We are located in Southern California, near Riverside at 2500 ft elevation. Hot summers and pretty cold winters. I have a picture of the room addition but am not sure how to post it...we had it built 6-7 years ago. The sales guy swore heat wouldn't be a problem with the special glass he sold us. Well, the glass doesn't get hot, but the frame sure does. We are considering roofing it over so it's useable. I'll try to figure out how to post a picture..

Ok...still waiting for 4 Seasons to get back to me about any experience they have with this. Might not be fixable and have to accept it isnt a 4 seasons room, just 2 seasons. Thank you, everyone for your input!

+1 to the other comments. Your experience is really just an inherent property of the material, not much can be done unfortunately. Even "thermally broken" aluminum is pretty conductive in comparison to other materials.

Google "Ceramic Insulating Paint".... Its not a magic bullet but it will help.. I would suggest a white color to help reflect the hot sun..

Ceramic paint is filled with tiny microscopic hollow spheres that trap air.

I would strongly suggest you do some research on this product before buying it to make sure it will do what is needed in your application.. I have no experience with it.
