ASP MVC 5: ViewBag does not exist in the current context

After upgrading one of my client’s applications from ASP MVC 4 to ASP MVC 5, We had designers errors related to Html Helpers and ViewBag in cshtml pages.

To fix those issues make sure you do the following:
Install Asp.NET Web Helpers Library from Nuget
Open the Web.config of the project and update the bindings if they haven’t been updated when installing the Nuget packages for example

<dependentAssembly>
<assemblyIdentity name=”System.Web.Mvc” publicKeyToken=”31bf3856ad364e35″ />
<bindingRedirect oldVersion=”0.0.0.0-5.2.2.0″ newVersion=”5.2.2.0” />
</dependentAssembly>

 

Find “webpages:Version” in the appsettings and update it to version 3.0.0.0. My web.config had

<add key=”webpages:Version” value=”2.0.0.0″ />

and I updated it to

<add key=”webpages:Version” value=”3.0.0.0″ />

Restart Visual Studio and rebuild. You may have to delete the bin folder for your project
