I'm using RequiresJs and RequiresCss and RenderJsHere and RenderCssHere, and the right files are getting added to my page. But, they're not being bundled or minified.

master.cshtml:

Html.RequiresCss("~/css/slick.css", 1)
    .RequiresCss("~/css/jquery.fancybox.css", 2)
    .RequiresCss("~/css/main.css", 3);

Html.RequiresJs("~/scripts/slick.js", 1)
    .RequiresJs("~/scripts/jquery.fancybox.js", 2)
    .RequiresJs("~/scripts/main.js", 3);

rendered as:

    <link href="/css/slick.css?cdv=1" type="text/css" rel="stylesheet"/><link href="/css/jquery.fancybox.css?cdv=1" type="text/css" rel="stylesheet"/><link href="/css/main.css?cdv=1" type="text/css" rel="stylesheet"/>

    <script src="/scripts/slick.js?cdv=1" type="text/javascript"></script><script src="/scripts/jquery.fancybox.js?cdv=1" type="text/javascript"></script><script src="/scripts/main.js?cdv=1" type="text/javascript">
</script>

ClientDependency.config

  <compositeFiles defaultProvider="defaultFileProcessingProvider" compositeFileHandlerPath="~/DependencyHandler.axd">
    <fileProcessingProviders>
      <add name="CompositeFileProcessor"
           type="ClientDependency.Core.CompositeFiles.Providers.CompositeFileProcessingProvider, ClientDependency.Core"
           enableCssMinify="true"
           enableJsMinify="true"
           persistFiles="true"
           compositeFilePath="~/App_Data/TEMP/ClientDependency"
           bundleDomains="localhost:123456"
           urlType="Base64QueryStrings"
           pathUrlFormat="{dependencyId}/{version}/{type}"/>
    </fileProcessingProviders>

What am I missing?
