I'm following this video tutorial:

My application does not appear to be rendering Kendo CSS properly. 

Here is my BundleConfig.cs

    public class BundleConfig
        // For more information on bundling, visit
        public static void RegisterBundles(BundleCollection bundles)
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(

            bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(

            // Use the development version of Modernizr to develop with and learn from. Then, when you're
            // ready for production, use the build tool at to pick only the tests you need.
            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(

            bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(

            bundles.Add(new ScriptBundle("~/bundles/kendojs").Include(

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

            bundles.Add(new StyleBundle("~/Content/kendocss").Include(

            bundles.Add(new StyleBundle("~/Content/dashboardcss").Include(

            bundles.Add(new StyleBundle("~/Content/backlogcss").Include(

            bundles.Add(new StyleBundle("~/Content/detailcss").Include(


Here is the head tag in my _Layout.cshtml:

    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>RPS Project Tracker</title>
    @RenderSection("styles", required: false)


    @RenderSection("scripts", required: false)

Here's some examples of the errors in my UI:

in /Backlog/{id}/Details view, my DropDownListFor has no styling attributes:


On the Dashboard and Backlog pages, my buttons have broken styling:

Inside DevTools, I'm getting the following error:


Any help sorting this out is greatly appreciated.

Hello Justin,


Thank you for writing to us.

There is a line in the definition which reads:


But I suppose it needs to be:


That should resolve the issue. For your convenience, I am also sending a full working MVC project with CDN references.
