Bundles can be called at View(.cshtml) page like:
@Scripts.Render("~/bundles/bundleName")
Replace bundleName
with your bundle name & it will render all js files in bundle on that page.
Make sure you use render statement in start of html body.
UPDATE:
It's basic advantage of using bundling you can manage version of js with build. Just edit bundlename to add release number & voila all you client were forced to get bundle since it's name is different. We are doing like this.
Earlier we need to manually minify js & added version number to files names too that was configured in web config files. That was painful, bundling is cherry on cake.
