Unobtrusive JavaScript and Ajax in MVC 3

In the previous release of the ASP.NET MVC which is (MVC 2) I didn't like the Ajax usage, like Ajax action link and Ajax begin form and I make a rule for the previous project for all my team memebers, that it is prohibited to use any of them, Why?? Because they generate inline JavaScript which is the same way as the web form does, this one of the reason that makes me hit the web form approach. So why I use them isnted of I can makes a clean JQuery code to follow JavaScript Unobtrusive JavaScript which means that we should keep our JavaScript code separated in. js file, as the CSS it must be separated from the html, the JavaScript also must be separated from html But in MVC 3 I surprised that all Ajax action not generate inline scripts and use JQuery and custom html attributes, we just reference unobtrusive-ajax.js file and of course the JQuery library, which I can consider it (unobtrusive) as a JQuery plugin, so now I really consider using Ajax helper method in my next proejct

This really show us how Microsoft not only imporove the MVC itself but also how they try to follow and lead the web community again as before :-)

Thanks Microsoft Keep Improving
