Validation via AJAX on ASP.NET 3.5?

I'm using ASP.NET 3.5 which has built in AJAX. I was disappointed to see they didn't have any AJAX controls like Validations. Most of the 3rd party AJAX validation controls were made for .NET 2.0. Is there anything native I can do with 3.5 to accomplish AJAX validation? For example, validating against a database or running a method against the form values?
