What's the point of ASP.net AJAX in ASP.net MVC?
So ASP.net MVC by default ships with both JQuery and ASP.net Ajax. While the use cases of JQuery are obvious and plenty, I just wonder what the point of ASP.net Ajax is? If I just have my Controller Actions return JSON, I don't need it? Also, any "old" ASP.net controls only work if you use the Webforms view Engine (I think I want to use another one, but that's not the point).
What has ASP.net Ajax to offer in an MVC Environment?
