Hello,

I just recently upgraded MVC to 5.2.7. I installed MVC using Nuget. Upon running my project, I receive the following error: 

Method not found: 'System.Web.Routing.RouteValueDictionary System.Web.WebPages.TypeHelper.ObjectToDictionaryUncached(System.Object)'.

[MissingMethodException: Method not found: 'System.Web.Routing.RouteValueDictionary System.Web.WebPages.TypeHelper.ObjectToDictionaryUncached(System.Object)'.]

There is another post on this issue, but I have tried the recommendations and haven't found a solution (https://stackoverflow.com/questions/21376261/mvc-5-1-missingmethodexception-system-web-webpages-typehelper-objecttodictionary).

He mentioned to replace the System.Web.Webpages, which I tried and did not work.

Here is my current Web.config 

 <dependentAssembly>
    <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
  </dependentAssembly>

  </dependentAssembly>
  <dependentAssembly>

    <bindingRedirect oldVersion="0.0.0.0-5.2.7.0" newVersion="5.2.7.0" />
  </dependentAssembly>

I need to keep the new version of MVC in order to use Telerik.

What else can I try? I have tried reinstalling MVC, modifing the Web.WebPages dll?

Any help is much appreciated I am confused!

    Hi @Eli Hellmer ,
    Have you tried cleaning and rebuilding the solution?
    You can try to clear the package directory and download it again.
    Check the Web.config and packages.config and web.config files in the Views folder.
    You can refer to this tutorial.
