jQuery, JSON objects and .NET WebServices

I have a question about creating JSON from JQuery, sending the same by Ajax to a webservice in .NET, and how to deserialize in .NET and save to the database.

Maybe someone can give me a hand to see where I'm mistaken!

jQuery and JSON:

var myObject = {};

//** BusinessPartner **
//function BusinessPartner(prefix) {
//    this.bpCodigo = $(prefix + " option:selected").val();
//    this.bpNombre = $(prefix + "-infonombre").text();
//
//** Locations **
//function Locations(prefix) {
//    this.locCode = $(prefix + " option:selected").val();
//    this.locName = $(prefix + "-name").text();

var oNewObject = new BusinessPartner("#bp-01");
var oNewObject2 = new BusinessPartner("#bp-02");

var myLocation = [];
var oOrigin = new Locations("#receipt");
myLocation.push(oOrigin);
var oDestination = new Locations("#portloading");
myLocation.push(oOrigin);

myObject["Agent1"] = oNewObject;
myObject["Agent2"] = oNewObject;
myObject["Locations"] = myLocation;

$.ajax({
    type: "POST",
    url: "Services/ActionsDb.asmx/saveData",
    contentType: "application/json; charset=utf-8",
    data: JSON.stringify(myObject),
    datatype: "json",
    success: function (response) {
        // After correct save send OK message.
    },
    error: function (xhr, status) {
        alert("An error occurred: " + status);
    }
});

The class in C# .NET

As I understand it, that should have exactly the same format as JSON received by the webservice.

public class Agent
{
    public string bpCodigo { get; set; }
    public string bpNombre { get; set; }
}
public class Location 
{
    public string locCode { get; set; }
    public string locName { get; set; }
}
public class oGet
{
    public Agent oCliente { get; set; }
    public Agent oCliente2 { get; set; }
    public List<Location> oLocations { get; set; }
}

Webservice

Good, now the WebService ActionsDb.asmx / savedata that will be asked to save the data in the DB.

    [WebMethod(EnableSession = true)]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public string saveData(oGet myObject)
    {
        try
        {
            string sClienteName = myObject.oCliente.bpNombre.ToString();
            return sClienteName.ToString();

        }
        catch (System.Exception ex)
        {
            return ex.Message.ToString();
        }
    }

Result

The error I get follows:
