Is Microsoft.ajax.js required for ASP.NET MVC ajax?

Question

You need to include javascript microsoft.ajax files to use the code, for example:

@Ajax.BeginForm() 

Answer 1

No, this is no longer necessary. ASP.NET MVC 3 uses jquery by default. So you will need jquery.unobtrusive-ajax.js , which modifies the data- * HTML5 attributes generated by the Ajax.* Helpers. Therefore, no more than MicrosoftAjax*.js .
