我正在研究一个 MVC 解决方案，该解决方案分为多个单独的程序集，其中一个仅包含视图。

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 找不到我的任何助手。帮助文件 (HeaderHelper.cshtml) 位于我的 App_Code 文件夹中。

这是我要使用的 Helper 示例：

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

在我看来，这就是我想如何称呼我的助手：

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

但是我收到编译错误“当前上下文中不存在名称 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 文件中的问题有关，这是它的内容：

@helper 指令自 beta 4 以来已被删除，因为它对其他 Razor 功能施加了太多限制：https ://github.com/aspnet/Razor/issues/281 。
