I am trying to convert a MVC4 view to Pdf. after a few minutes searching I found
https://www.nuget.org/packages/Rotativa/
and
https://www.nuget.or
I had the same problem with asp.net mvc 4 and Rotativa. Adding a binding redirect for System.Web.Mvc in my web.config solve the problem for me.
<runtime>
    <dependentAssembly>
       <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
           <bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
           </dependentAssembly>
    </assemblyBinding>
</runtime>
