Cannot find DataContractJsonSerializer from an Asp.Net Mvc application

Question

I can't get access to the DataContractJsonSerializer method from System.Runtime.Serialization.Json

If I do:

using System.Runtime.Serialization.Json;

I get an error...

How can I access this in my Asp.Net Mvc app so I can use the DataContractJsonSerializer method
