首先 - 我已经搜索了SO并发现许多问题同样的事情,虽然只是添加<add namespace="System.Web.Mvc.Html" />我的web.config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站点的_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:
<system.web.webPages.razor>
<host factoryType="System.Web.WebPages.Razor.WebRazorHostFactory, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.WebPages.WebPage">
<namespaces>
<add namespace="System.Web.Helpers" />
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Optimization" />
<add namespace="System.Web.Routing" />
<add namespace="System.Web.WebPages" />
</namespaces>
</pages>
</system.web.webPages.razor>
如果我将其更改为使用版本5,那么我会收到程序集(v5)无法找到的错误等.
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
<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
<section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
<section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
</sectionGroup>
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:
顺便说一句,没有必要对配置文件进行任何更改,简单的清理和重建解决方案也不起作用.
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\临时 ASP.NET 文件
和重建？
