Type 'Store.WebUI.Entities.ShippingDetails' is not defined & 'BeginForm' is not a member of 'Html'.

Hi

Jeg havde nogle vb-net-late-binding-operations-cannot-be-converted-to-an-expression-tree fejl men fik det løst ved at andre min @Page til
<%@ Page Language="vb" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage(Of Store.WebUI.Entities.ShippingDetails)" %>

Nu får jeg så bare de to fejl som skrevet i overskriften:
Type 'Store.WebUI.Entities.ShippingDetails' is not defined & 'BeginForm' is not a member of 'Html'.

Min code er:
<%@ Page Language="vb" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage(Of Store.WebUI.Entities.ShippingDetails)" %>
