Custom JavascriptConvert Not Being Registered

Question

I built a custom javascript converter, but it is not being called when I call my webservice.

namespace LoanPal.WebServices.Converters { public class ContactConverter : JavaScriptConverter { public ContactConverter() {

    }

    public override object Deserialize(IDictionary<string, object> dictionary, Type type, JavaScriptSerializer serializer)
    {
        if ((dictionary != null) && (type == typeof(Contact)))
        {
            Contact contact = new Contact();

            contact.Id = serializer.ConvertToType<int>(dictionary["Id"]);

            return contact;
        }

        return null;
    }

    public override IDictionary<string, object> Serialize(object obj, JavaScriptSerializer serializer)
    {
        Contact contact = obj as Contact;

        Dictionary<string, object> result = new Dictionary<string, object>();

        if (contact != null)
        {
            result.Add("Id", contact.Id);
            return result;
        }

        return result;
    }

    public override IEnumerable<Type> SupportedTypes
    {
        get { return new List<Type>(new Type[] { typeof(Contact) }); }
    }
}

}

I registered it in the web.config

<system.web.extensions>
    <scripting>
        <webServices>
            <jsonSerialization maxJsonLength="10000">
                <converters>
                    <add name="ContactConverter" type="LoanPal.WebServices.Converters.ContactConverter, App_Code" />
                </converters>
            </jsonSerialization>
        </webServices>
    </scripting>
</system.web.extensions>

Then I am making a WCF call but it isnt hitting it with a breakpoint.

    [OperationContract]
    [PrincipalPermission(SecurityAction.Assert, Role = "LoanOfficer")]
    [WebGet(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
    public ContactProxy SaveContact(ContactProxy contactProxy)
    {
        return contactProxy;
    }

Any ideas?
