I have a custom there, where I try to require some of my css and js files via the ResourceManifest.cs file - I keep into running a quite weird issue tough.

I get the following error:

a 'script' named 'FoundationScript' could not be found

This is my ResourceManifest.cs:

using Orchard.UI.Resources;

namespace Themes.TestTheme
{
  public class ResourceManifest : IResourceManifestProvider
  {
    public void BuildManifest(ResourceManifestBuilder builder)
    {

      var manifest = builder.Add();

      manifest.DefineStyle("Foundation").SetUrl("foundation.min.css");
      manifest.DefineScript("FoundationScript").SetUrl("foundation.min.js");

    }  
  }
}

In the Layout.cshtml, I have following:

@{
  Script.Require("ShapesBase");
  Script.Require("FoundationScript");

  Style.Include("site.css");
  Style.Require("Foundation");

}

What am I missing here?
