JSON WebMethod not working in Sitefinity

  • JSON WebMethod not working in Sitefinity
  • Hi there,


    I've sitefinity hosted in asphostportal.com. then I am trying to call via ajax a WebMethod hosted in a traditional ASP.Net
    WebForm code-behind page. Here is the code for the WebMethod:

    public static object States()

        StateProvince[] states = new StateProvince[] ;
        ApplicationServiceClient proxy = null;

            proxy = new ApplicationServiceClient();
            states = proxy.GetStateProvinces();
        return states;


    The WebMethod works just fine in my stand-alone development environment or if deployed normally to IIS, but when I deploy the aspx page to Sitefinity, I get the following exception when it's called:
    Server Error in '/' Application.
    Unknown web method States.aspx.
    Parameter name: methodName
    I'm not sure if Sitefinity is hijacking the URL and post-pending the ".aspx" or what is going on here.
    Here is the jquery call that is calling the web method:

            type: "POST",
            contentType: "application/json; charset=utf-8",
            url: "Regions.aspx/States",
            data: "",
            success: function(data)
                // implementation omitted
            error: function(xhr, msg)

    I can replicate the problem by posting the request manually using Fiddler.
    Again, this works just fine everywhere except when deployed to Sitefinity. Anybody have any thoughts?
