The name 'ViewBag' does not exist in the current context mvc 5 - asp.net

Question

I have web.config inside the Views folder
<?xml version="1.0"?>
<configuration>
<configSections>
<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>
</configSections>
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.2.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
<add namespace="PartyInvites" />
</namespaces>
</pages>
</system.web.webPages.razor>
<appSettings>
<add key="webpages:Version" value="3.0.0.0" />
</appSettings>
<system.webServer>
<handlers>
<remove name="BlockViewHandler"/>
<add name="BlockViewHandler" path="*" verb="*" preCondition="integratedMode" type="System.Web.HttpNotFoundHandler" />
</handlers>
</system.webServer>
</configuration>
I also make sure the solutions Web.config is updated
<dependentAssembly>
<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
<bindingRedirect oldVersion="1.0.0.0-5.2.2.0" newVersion="5.2.2.0"/>
</dependentAssembly>
But when i look at the views, i still get the error
Compiler Error Message: CS0103: The name 'Viewbag' does not exist in
the current context

Answer 1

Looks like my issue is an isolated case, VS tells me it get screwed after i updated some extension, i cannot remember what extension made it like this so i just repaired the installation of VS and it worked.

Answer 2

I had the same issue on Visual Studio 2015. It was resolved by updating the .Net Framework to use 4.5.2 instead of 4.0. This is done in the Properties page of the project.

Answer 3

I had this issue regardless of having all the correct configuration done in the web.config file.
Found out to be some bad files in the Component Cache, preventing the Razor views from recognising ViewBag, Model, and HtmlHelpers. Deleting these files solved the problem (good versions of these files were created next time I opened Visual Studio).
Please follow below path to discover the files:
C:\Users\your.name.here\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache
Delete all four files:
Microsoft.VisualStudio.Default.cache
Microsoft.VisualStudio.Default.catalogs
Microsoft.VisualStudio.Default.err
Microsoft.VisualStudio.Default.external
I closed my project, deleted the files on that path and reopened my project, cleaned the solution and built it again and the problem was solved
Deleting your Temporary ASP.NET Files also helps. C:\Users\your.name.here\AppData\Local\Temp\Temporary ASP.NET Files.
Thanks!
