I have the following code in a Partial View Macro file (HeroCarousel.cshtml).

@*inherits Umbraco.Web.Macros.PartialViewMacroPage*@
@inherits umbraco.MacroEngines.DynamicNodeContext
@using The_Drum.App_Code
@{
    if(Utilities.getXMLNode("HeroCarouselFolderID") != null)
    {
        //Get the id of the carousel images folder
        var carouselFolderID = Utilities.getXMLNode("HeroCarouselFolderID");
        //Get the media folder as a dynamic node
        var mediaFolder = Library.MediaById(carouselFolderID);
        if (mediaFolder.Children.Any())
        {
            //for each item in children of the selected media folder
            foreach (var mediaItem in mediaFolder.Children)
            {
                <a href="#!" class="img"><img src="@mediaItem.umbracoFile"  alt="@mediaItem.Name"/></a>

            }
        }
    }

}

When I try and use in my template like so

@Umbraco.RenderMacro("HeroCarousel")

it errors:

Error loading Partial View script (file: ~/Views/MacroPartials/HeroCarousel.cshtml)

I think this is because the file needs to inherit from "Umbraco.Web.Macros.PartialViewMacroPage", but I need the methods and properties from "inherits umbraco.MacroEngines.DynamicNodeContext" - HOW DO I FIX THIS PLEASE?
