Instead of using all of these includes, check your BundleConfig and see if they are bundled there.
It should look something like:
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new ScriptBundle("~/bundles/MyBundle").Include(
"~/Scripts/jquery-{version}.js",
"~/Scripts/jquery.unobtrusive-ajax.js",
"~/Scripts/jquery-ui-{version}.js"
));
}
Using Razor syntax, take out all your HTML <link /> tags and add:
@Scripts.Render("~/bundles/MyBundle")
The same can by used for Styles by the way, except the tag is:
@Styles.Render("~/bundles/MyStyles")
This might-well resolve your issue.
