title: Parsing JSON string to values
body: <p>I'm not allowed to import new packages at the customer. I'm only allowed in the area between obtaining a <code>String</code> object looking like a JSON string and a return, where I'm supposed to return some parts of it in a <code>List&lt;String&gt;</code>.</p>
  
  <p>I feel terribly limited and as far I can see, I can't proceed. My best bet is using <code>Regex</code> object but perhaps there's a smoother solution? (I believe I'm allowed to use XDocument too, and LINQ, if that's of any help).</p>
  
  <p>Suggestions?</p>
