Intellisense not working for Razor Views

Donnerstag, 4. Februar 2016

Sometimes when you upgrade ASP.NET MVC (e.g. from 4.0 to 5.x), you also update your WebPages Version (e.g. from 2.0 to 3.0) and then you encountered following error message:

The name 'ViewBag' does not exist in the current context

Usally this works after verifiying you have these lines in root web.config:

<add key="webpages:Version" value="3.0.0.0" />

and

 <dependentAssembly>
 <assemblyIdentity name="System.Web.Razor" publicKeyToken="31bf3856ad364e35" culture="neutral" />
 <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
 </dependentAssembly>

   <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
 </dependentAssembly>

Be aware there is also a web.config in your views folder, which has to be update to WebPages 3.0
