I'm using .NET 2.0 and Visual Studio 2005 to try to create a web service that can be consumed both as SOAP/XML and JSON. I read Dave Ward's Answer to the question How to return JSON from a 2.0 asmx web service (in addition to reading other articles at Encosia.com), but I can't figure out how I need to set up the code of my asmx file in order to work with JSON using jQuery.

Two Questions:

• How do I enable JSON in my .NET 2.0 ASMX file?
• What's a simple jQuery call that could consume the service using JSON?

Also, I notice that since I'm using .NET 2.0, I i'm not able to implement using System.Web.Script.Services.ScriptService.

Here's my C# code for the demo ASMX service:

using System;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;


/// <summary>
/// Summary description for StockQuote
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class StockQuote : System.Web.Services.WebService {

    public StockQuote () {

        //Uncomment the following line if using designed components 
        //InitializeComponent(); 

    }

    [WebMethod]
    public decimal GetStockQuote(string ticker)
    {
        //perform database lookup here
        return 8;
    }

    [WebMethod]
    public string HelloWorld() {
        return "Hello World";
    }        
}

Here's a snippet of jQuery I found on the internet and tried to modify:

    $(document).ready(function(){
        $("#btnSubmit").click(function(event){
            $.ajax({
                type: "POST",
                contentType: "application/json; charset=utf-8",
                url: "http://bmccorm-xp/WebServices/HelloWorld.asmx",
                data: "",
                dataType: "json"
            })
            event.preventDefault();
        });
    });
