title: Basic Simple Asp.net + jQuery + JSON example
body: <p>I'm trying to learn how to make a simple call to the server from Javascript/jQuery. I've been trying to learn and could not find a tutorial with those simple steps. </p>
  
  <p>I want to send a message to the server with two parameters (a DateTime and a String) and get back a DateTime. I want to do that via JSON.</p>
  
  <ul>
  <li>How would the code in the server look like (structure only)? </li>
  <li>Is there something special I should do on the server side? And how about security?</li>
  <li>How would I implement the call in jQuery? </li>
  <li>And how would I handle the result?</li>
  </ul>
  
  <p>I'm most interested on code structure.</p>
  
  <p><strong>Update</strong></p>
  
  <p>I found the answer below great to get me started. However, I recently stumbled upon <a href="http://www.search-this.com/2010/04/26/asp-net-linq-jquery-json-ajax-oh-my/">Full ASP.NET, LINQ, jQuery, JSON, Ajax Tutorial</a>. It's just a fantastic and very didactic step-by-step that I want to share with anyone else who comes across this question in the future.</p>
