Just spent a lot of my time trying to intersect Kendo UI and ASP.NET Bundler. The crack of them problem is that kendo scripts are minified by default and Bundler's default behavior is not to render minified scripts.

The solution is to clear the IgnoreList of bundle collection.

bundles.IgnoreList.Clear()

Let's abstract it away, though:

  private static void AllowMinifiedFilesInDebugMode(BundleCollection bundles)
        {
            bundles.IgnoreList.Clear();
        }

Hope it helps.
