title: JSON Rpc libraries for use with .NET
body: <p>I am looking into <a href="http://en.wikipedia.org/wiki/JSON-RPC" rel="nofollow">JSON RPC</a> libraries for .net that are free to use in commercial applications. Up until now i just seem to have found <a href="http://code.google.com/p/jayrock/" rel="nofollow">JROCK</a>.</p>
  
  <ol>
  <li><p>What other libraries, architecture have i got similar to JRock for <strong>.NET 2.0</strong></p></li>
  <li><p>What is the difference between a <code>[WebMethod]</code> in <code>asmx</code> web-service returning a instance of a class and a JSON Rpc method as in the JRock website page. Do i have any usability benefits, performance benefits or any benefits of using one over the other</p></li>
  </ol>
