Firstly - I have scoured SO and found many questions asking the same thing, though simply adding <add namespace="System.Web.Mvc.Html" />
in my web.config didn't cure the issue...
Ok, so I have started a new project, based on the template Angular SPA - link is here:
http://visualstudiogallery.msdn.microsoft.com/5af151b2-9ed2-4809-bfe8-27566bfe7d83
I have upgraded the MVC to version 5 & the webApi to version 2 - to fall in line with other projects in the solution.
Now, in the _layout page of the SPA site I am trying to use the @Html.ActionLink
helper, though keep getting the error 'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'ActionLink
I am sure this is all down to some web.config configuration - some kind of conflict between what packages I have installed and what is setup in the config from the template.
In particular, this part:
<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>
If I change this to use version 5 then I get the error that the assembly (v5) could not be located etc.
I am running out of ideas on how to resolve this conflict.
Here are the config sections from my SPA web.config
<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>
If I change the version to 5, I get the error below:
