At this moment, I will tell you about working with CDN bundle config in ASP.NET MVC 6. ASP.NET MVC includes nice attributes and Bundling is part of them. The Bundling and Minification attributes let you scale back quantity of HTTP requests that the web site wants in order to make by combining individual scripts and style sheet files. Additionally it may scale back a general scale bundle by minifying the content material of software. From ASP.NET MVC 4 bundling also contains CDN assistance also where one can utilize public CDN accessible for typical libraries. Let’s look this attributes in particulars.

Libraries such as jQuery, jQuery UI and a few some other libraries are commonly utilized in a lot of the applications. There will be accessible in CDN (Content Delivery Networks) specifying the URL of specific library along with particular version. Bundling now has CDN path as parameter in default bundle functionality where one can specify the path from the CDN library and utilize that. Thus whenever you application operate in production environment first it'll verify regardless of whether CDN can be found or otherwise in case accessible and then it can load it coming from the CDN itself and In case CDN isn't accessible and then it can load files hosted on server. CDN will use the distributed network when enabled, and in optimization mode. You can’t combine multiple CDN’s together (you can only use 1 script). By default. UseCdn is set to false.

And First, you need to Enable UseCdn feature:
bundles.UseCdn = true;

Now, Add the jQuery Bundle from the CDN Bundle with the code bellow:
var jqueryBundle = new ScriptBundle("~/bundles/jquery", "http://code.jquery.com/jquery-2.0.3.min.js").Include(
                "~/Scripts/jquery-{version}.js");
            jqueryBundle.CdnFallbackExpression = "window.jquery";
            bundles.Add(jqueryBundle);

The CdnFallbackExpression is used when even CDN server is unavailable. And next step, this is CDN bundle config:
bundles.UseCdn = true;
            var jqueryBundle = new ScriptBundle("~/bundles/jquery", "http://code.jquery.com/jquery-2.0.3.min.js").Include(
                "~/Scripts/jquery-{version}.js");
            jqueryBundle.CdnFallbackExpression = "window.jquery";
            bundles.Add(jqueryBundle);
