In the asp.net mvc 4.0 intranet project I see this in the _layout.cshtml:
<script src="@System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/Scripts/js")"></script>
What means /Scripts/js ?
My question is about the "js"!
This is part of the optimization framework which minifies and bundles your JavaScript for you. This include assumes the default registration. For more introduction, see Scott Guthrie's blog post.
