  Compiler Error Message: CS1061: 'System.Web.Mvc.HtmlHelper&lt;LC.TLAdminMVC.DAL.BusinessObjects.CompanySingleViewModel&gt;' does not contain a definition for 'Configurator' and no extension method 'Configurator' accepting a first argument of type 'System.Web.Mvc.HtmlHelper&lt;LC.TLAdminMVC.DAL.BusinessObjects.CompanySingleViewModel&gt;' could be found (are you missing a using directive or an assembly reference?)
