"在MVC 3视图中,当前上下文中不存在名称'HTML'

Question

我开始使用"MVC 3",但我面临一些小问题.在我的视图中,当我编写这样的代码时:

@if(Request.IsAuthenticated) {
    <text>Welcome <b>@Context.User.Identity.Name</b>!
    [ @Html.ActionLink("Log Off", "LogOff", "Account") ]</text>
}
else {
    @:[ @Html.ActionLink("Log On", "LogOn", "Account") ]
}

像@Request和@Html这样的对象表示错误:The name 'HTML' does not exist in the current context.

@ Context,@ ViewBag,@ Layout,@ Url等也会出现同样的情况.

看到:

但代码编译正确,没有错误.问题是我不能在视图中使用Intellisense和thisses对象.这是正常的吗？(我不这么认为).可能会发生什么？

我重新安装了MVC 3框架,但仍然会发生同样的情况.

注意:这是一个从头开始的新项目,而不是MVC 2迁移.使用Razor引擎和ASPX都会发生这种情况.

这是Views文件夹中的Web.Config:
