I have orcas installed on my development machine and I'm developing with asp.net ajax. I installed .net 3.0 and 3.5 on my server, but when I port my project over to my server I still get the "aspcriptManager unrecognized tag" ordeal. So I installed orcas on the server in case there were other dependencies that I was missing, and sure enough the problem went away.

This is a test server that I can mess around with, but I'd like to avoid installing orcas on the production server. What should I install in order that asp.net ajax works without orcas?
