title: Sample code for JSON-RPC client in C#
body: <p>I need a simple JSON-RPC 1.0 client in C#, preferably using .NET 2.0 or later.
  I checked out JRock 0.9
  They have several samples including Yahoo reader, but the samples demo JSON, not JSON-RPC.
  I understand I could implement RPC part using any of the available JSON parsers, like JRock or two from Microsoft. I would prefer a ready sample.</p>
