Using jQuery in ASP.NET

Solution
No, you don't need ASP.NET AJAX installed to use the AJAX functionality of jQuery.
You can call PageMethods and Web Services without needing a `ScriptManager` control (which generates the JavaScript proxy objects that allow you to use familiar syntax to call web services and page methods).

Problem
When using the AJAX functionality in jQuery, do I also have to have ASP.NET AJAX/.NET 3.5 installed also? or can I only use ASP.NET AJAX? I'm unclear on whether or not I'm able to use AJAX in ASP.NET without ASP.NET AJAX or not.
