Hi, How can I access an IUmbracoContextFactory such as umbracohelper in an static class.

So basically, I want to render a grid and I have an HtmlHelperExtention class with an GetGridHtml method and I want to query the content by its unique identifier.

public static MvcHtmlString GetGridHtml(this HtmlHelper html, IUmbracoContextFactory Umbraco, int id, string propertyAlias = "contentGrid", string framework = "ContentGrid")
        {
            using (var cref = Umbraco.EnsureUmbracoContext())
            {
                var cache = cref.UmbracoContext.Content;
                var property = cache.GetById(id);
                return html.GetGridHtml(property, propertyAlias, framework);
            }            
        }

But i am getting an error when I want to use this extention method from my razor view

@Html.GetGridHtml(this.UmbracoContext, Model.Id)

Whats the best practice of passing in the umbraco context object to extention static class?
