Thanks , Resolved had to remove all Previous refrences of mvc3 and re-refrence it again from /ProgramFiles/ASP.NET MVC 3/System.Web.Mvc.dll as on default it shows assemblies of only mvc4

There is another way to resolve the "Entry point not found exception", you can add the following section in your

<runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <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>

This will instruct the runtime to use MVC4 binaries. We are using this in our projects without any exceptions.
