Bundle virtual-paths should not be duplicated, otherwise the dupe will overwrite the contents of the previous entry. To add more than one file to a bundle, wrap them in the params in the Include method.

For example, in BundleConfig.cs RegisterBundles, this:

bundles.Add(new StyleBundle("~/bundles/css").Include("~/Content/xxx.less"));
bundles.Add(new StyleBundle("~/bundles/css").Include("~/Content/yyy.less"));

Needs to be this:

bundles.Add(new StyleBundle("~/bundles/css").Include(

Also, the bundle virtual path depth should be the same as the depth of the file you are referring to (4 in the example below). If you don’t do this, relative paths in your less/css will fail.

	bundles.Add(new LessBundle("~/Content/xxx/less/yyy").Include("~/Content/xxx/less/yyy.less"));

using System.Web.Routing;

And be sure you add the RequestContext parameter to the GetControllerInstance method call like this:

protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)

How to eliminate magic strings from Html.DropDownListFor

Magic strings are just nuclear-powered bug magnets. They attract fat-fingering mistakes while coding and practically guarantee bugs will be introduced while refactoring. If you’re like me, you’ll hate the magic strings required in the Html.DropDownListFor as much as I do. Now there’s an easy way to get rid of them once and for all…
