The Aasimar are in the DM book as a playable option. Imo WoC screwed the pooch with making Tiefling a "common race" it rob them of their uniqueness. Valen Shadowbreath was a really cool character in nwn attached to a race that was as rare as a good aligned Drow. But now tiefling everywhere because of 4e retconned them and forced asmodeus on the fr pantheon. 4e was a mistake even because some writer didn'tike the word Aasimar we got the Deva thing instead of proper Aasimar.
