I have a few helpers from the past and i would like to use them on Orchard modul(widget, Views/Parts/someview.cshtml). Orchard dont see this. Maybe its problem in namespace registration. I register this as clasic MVC on web.config where views are.

Helper for example like this:
public static MvcHtmlString Image(this HtmlHelper html, string url, string alt, object htmlAttributes)
            var imgBuilder = new TagBuilder("img");
            imgBuilder.MergeAttribute("src", url);
            imgBuilder.MergeAttribute("alt", alt);
            imgBuilder.MergeAttributes(new RouteValueDictionary(htmlAttributes));
            string imgHtml = imgBuilder.ToString(TagRenderMode.SelfClosing);

            return MvcHtmlString.Create(imgHtml);
Use like this:
@Html.Image(item.URL, item.Name, new { @title = @item.Description })

All you have to do to use an extension method (and this is not specific to Orchard), is to add a using statement pointing at its namespace.

Arror appeared because the orchard uses shame, I was used to model from classical MVC. Compiller did not know the data types of item.
