‘System.Web.WebPages.Html.HtmlHelper’不包含’ActionLink的定义
首先 – 我已经搜索了SO并发现了许多问题同样的问题，尽管在我的web.config中添加并没有解决问题…
好的，所以我已经开始了一个基于模板Angular SPA的新项目 – 链接在这里：
http://visualstudiogallery.msdn.microsoft.com/5af151b2-9ed2-4809-bfe8-27566bfe7d83
我已将MVC升级到版本5，将webApi升级到版本2 – 与解决方案中的其他项目一致。
现在，在SPA网站的_layout页面中，我尝试使用@Html.ActionLink帮助程序，但不断收到错误'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'ActionLink
我确信这完全取决于一些web.config配置 – 我安装的软件包和模板配置中的设置之间存在某种冲突。
特别是这部分：
如果我将其更改为使用版本5，那么我会收到无法找到程序集（v5）的错误等。
关于如何解决这个冲突，我的想法已经不多了。
以下是我的SPA web.config中的配置部分
如果我将版本更改为5，我会收到以下错误：

我正在使用VS 2013 Pro Update 2.这对我有用：
- 关闭Visual Studio
- 删除bin和obj文件夹
- 重新打开解决方案并重建
- 视图上没有更多错误
顺便说一句，没有必要改变配置文件的任何内容，简单的清理和重建解决方案不起作用。
您是否尝试过清理解决方案，删除临时ASP.NET文件
C：\ WINDOWS \ Microsoft.NET \ Framework \ v4.xxxx \ Temporary ASP.NET Files
和重建？
我刚刚为Visual Studio 2013安装了更新2，我的问题就消失了。
