Answer :

You need to set webpages:Version appSettings with appropriate value. In your case it has to be 2.0.0.0... For this just go in Web config file and write / Change ....

<add key="webpages:Version" value="1.0.0.0"/> 

to 

 <appSettings>

    <add key="webpages:Version" value="2.0.0.0"/>

 </appSettings>

Done :)
