Once upon a time (in the CTP days), Wilco wrote a nice class browser that has been used for a while by the ajax.asp.net documentation site.

Eilon has written a new class browser that is more complete than Wilco's and that has the interesting particularity to build on top of a reflection layer for the AJAX library. Check it out.
