title: JSON.NET serialization trouble
body: <p>I have a class with property type of Point ( struct in .NET Framework).
  I use JsonConvert from Newton.Json to serialize it to JSON.
  But result is </p>
  
  <pre><code> "Point" : "100,100" 
  </code></pre>
  
  <p>Instead of </p>
  
  <pre><code> "Point" : { X: "100", Y: "100"}
  </code></pre>
  
  <p>When I replace JsonConvert with standard JavascriptSerializer,
  all works fine.</p>
  
  <p>But I want to use JsonConverter from JSON.Net, because it's much faster.</p>
