ASP.Net Ajax Ships

This is big news for a lot of people in the Ajax community. This is a free download. You can find more information at https://ajax.asp.net. We do not use ASP.Net Ajax on www.live.com (long story), but i do use it in my personal site. I have tried prototype and a couple of other Ajax libraries. I have to say i liked prototype best, for straight Ajax libraries. However, i find ASP.Net Ajax gives me great integration with ASP.Net which makes a lot more valuable for me.

How do you like ASP.Net Ajax? What have you built using this?
