title: JSON.NET on Ubuntu Linux
body: <p>I'm trying to start using JSON.NET for Mono on Linux and MonoDevelop. I found the packages in the repository, so I installed them using <code>sudo apt-get install libnewtonsoft-json-cil-dev libnewtonsoft-json-cil monodoc-newtonsoft-json-manual</code></p>
  
  <p>I have the following code to test if the installation worked:</p>
  
  <pre><code>using System;
  using Gtk;
  using Newtonsoft.Json;
  
  namespace jsontest
  {
      class MainClass
      {
          public static void Main (string[] args)
          {
              Application.Init ();
  
              Car my_car = new Car ();
              string json = JsonConvert.SerializeObject (my_car);
  
              MainWindow win = new MainWindow ();
              win.Show ();
              Application.Run ();
          }
      }
  
      public class Car
      {
          public string make;
          public string model;
  
          public Car()
          {
              make = "ford";
              model = "jalopy";
          }
      }
  }
  </code></pre>
  
  <p>When I try to run the program it gives me the following error: <code>The type or namespace name 'Newtonsoft' could not be found. Are you missing an assembly reference?</code></p>
  
  <p>Why can't MonoDevelop find the library I installed?</p>
