Should I learn ASP.NET AJAX, jQuery or both? [closed]

Question

I'm .NET developer. Most of my career I worked on web based intranet applications (ASP.NET WebForms) but always as a server side developer. Client side development was done by my colleagues more skilled in JavaScript and different JS frameworks. At the moment I have some JavaScript skills and very elementary understanding of both ASP.NET AJAX (I mean client side library) and jQuery. It mostly means that I can read JS code and I can write very simple functions. I would like to be better in this area and I'm planning to learn some of these technologies. Should I learn both ASP.NET AJAX and jQuery or skip ASP.NET AJAX and go directly to jQuery? By learning I mean really deep understanding of concepts and whole framework.

At the moment I'm reading Introducing Microsoft ASP.NET AJAX but I'm not very happy with it. It doesn't have coverage I would expect. I have already bought ASP.NET AJAX in Action and jQuery in Action. Do you recommend me any other sources?

Edit: So nobody defends ASP.NET AJAX? It looks like this API exists only to fill some MS certification exams.

Answer 1

jQuery is more than enough. Couple this with ASP.NET MVC and you will never ever need to look at Microsoft ASP.NET AJAX (or whatever its name is currently). Even if you work with standard ASP.NET WebForms, jQuery will be sufficient.

Also note that Microsoft have fully embraced jQuery (it is included with ASP.NET MVC) and they are actively supporting its development. I won't be surprised if MS AJAX becomes obsolete soon (for me personally it's been deprecated for years :-)).

So I would recommend you use the time you would have wasted in learning MS AJAX in improving your jQuery skills.

Answer 2

Try to learn ajax from scratch, with plain javascript, it helps you understand how it works. Then go to jQuery.
