title: How to convert object to JSON without JSON.NET library?
body: <p>I want to save this object:</p>
  
  <pre><code>Student s = new Student();
  </code></pre>
  
  <p>to Json file. But Visual Studio 2012 can't find none of these namespaces:</p>
  
  <pre><code>System.Web.Script;
  System.Json;
  System.Runtime.Serialization.Json;
  </code></pre>
  
  <p>Any idea?</p>
