Question

我正在开发一个MVC解决方案，它分为单独的程序集，其中一个只包含视图。

我遇到的问题是在我的视图中使用Html Helpers（用HTML编写，而不是C＃类）; Razor Intellisense没有找到任何帮助者。帮助文件（HeaderHelper.cshtml）位于我的App_Code文件夹中。

以下是我想要使用的助手的示例：

<!-- PAGE HEADERS HELPERS -->
@helper HelperPageHeader(String title)
{
    <div class="page-header text-center">
        <h3>@title</h3>
    </div>
}

以下是我想在我看来打电话给我的助手的方式：

@HeaderHelper.HelperPageHeader("Test HeaderHelper")
<div>
    <!-- HTML -->
</div>

但是我收到编译错误“当前上下文中名称HeaderHelper”。

我相信没有办法为我的HTML Helper设置命名空间。也许这个问题与我的web.config文件中的错误有关，这里是它的内容：

有什么想法吗？在此先感谢您的帮助！

@helper指令自beta 4后被删除，因为它对其他Razor功能施加了太多限制：Worksheet.Index property。
