1. Enable Ajax in ASP.NET MVC 5

In ASP.NET MVC5, Ajax is not enabled by default so Ajax.BeginForm won't work.

• Manage NuGet Packages > Install Microsoft jQuery UnobtrusiveAjax
• In BundleConfig.cs Add:

bundles.Add(new ScriptBundle("~/bundles/jqueryajax").Include(
                "~/Scripts/jquery.unobtrusive*"));

• In _Layout.cshtml add:

@Scripts.Render("~/bundles/jqueryajax")

That's it :)
