No intellisense on namespaces in Views Web.config

Question

I have a MVC5 project I am trying to solve some issues with where I am not getting intellisense on the System.Web.MVC components

In the Web.Config in my views folder I have the following;

<system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <pages pageBaseType="System.Web.Mvc.WebViewPage">
      <namespaces>
        <add namespace="System.Configuration" />
        <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="Helpers" />
        <add namespace="Common.Net.Mvc" />
        <add namespace="Common" />
        <add namespace="MvcSiteMapProvider.Web.Html" />
        <add namespace="MvcSiteMapProvider.Web.Html.Models" />
      </namespaces>
    </pages>
  </system.web.webPages.razor>

However when I then reference for example Url., ViewBag or Html.ActionLink etc(also if I reference my Common class which is a .resx generated file). I get errors saying they do not existing the current context.

I can compile and run the code successfully and the pages render just fine, it would be nice to eliminate these errors though and get the intellisense I usually get.

I am running VS2017 Community and I have the Razor extension installed and updated. I have intellisense on other projects it just seems to be this one.

Typically: rebuild; Close all files; Close Visual Studio and reopen — Ashley Medway, Oct 17 '17 at 16:06
Seem to be. There's no issue when running the program. Just annoying I can't get the intellisense? — Matthew Flynn, Oct 17 '17 at 16:18
Clear any .vs hidden folders and .suo .user files. Is it problem with only one solution? If you create a new MVC project does it work? All else fails try Visual Studio in SafeMode? — Ashley Medway, Oct 17 '17 at 16:19
Sorry Ashley, yes tried that but still nothing. Yes it I have intellisense on other projects, its just this one. there is a .vs folder outside the solution but its not hidden. I tried removing this also but it's still not registering. There couldnt be anything contained in the csproj could there? — Matthew Flynn, Oct 19 '17 at 07:34

Ok, After much searching and wasting of time, this answer here fixed the issue;

The name 'ViewBag' does not exist in the current context - Visual Studio 2015

Here is a run down of the steps I took (the removal and deletion of files may not be required);

Delete the .suo and .csproj.user from the solution having the issues.
Delete the hidden .vs folder form the route of the solution
Delete the temp asp net files from

C:\Users\your.name.here\AppData\Local\Temp\Temporary ASP.NET Files

Delete the files fro here;

C:\Users\your.name.here\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache

Note the above alone didn't fix so then I applied the following in conjunction witht he above.

Compared the .csproj version info with that of the project with the issue and ammend (as it was indeed a project carried over form VS 2012) and as per the link above.

Right click the solution -> 'Manage Nuget Packages...' -> Updates -> select all -> apply updates

This rebuilt the nuget references and the intellisense came back. Hopefully one day, somewhere this will help.
