WebMethod works in Visual Studio but not on IIS7 (HTTP Status 500)

Question

I have a WebMethod which I call through Ajax. The code works perfectly through Visual Studio, however once I release it to IIS7 and login, I receive an Internal Server Error (HTTP status 500).

Using Fiddler I see the following:

Could not load file or assembly 'System.Web.Extensions, Version=4.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

I think I maybe need something in the web.config, but I am not sure.

Here is the code:

AJAX

function GetProgressStatus() {
        $.ajax({
            type: "POST",
            url: paths + '/webmethods.asmx/Gety',
            data: "{}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            processData: false,
            traditional: true,
            success: function (msg) {
                for (var i = 0; i < 13; i++) {
                    SetValueToBox(msg.d[i], i + 2);
                    SetNumberColor(i + 2);
                }
            }
        });

WebMethod

[System.Web.Services.WebMethod(BufferResponse = false, EnableSession = true)]
    public object Gety()
    {

        if (HttpContext.Current.Session["LoggedInUserType"].ToString() == GlobalVaribles.UserLogged)
        {
            var viewUserDashboardCountsValueBussinessLogicLayer = new ViewUserDashboardCountsValueBLL();
            var userDashboardValues =
                 viewUserDashboardCountsValueBussinessLogicLayer.GetUserDashboardCountByUserId(Convert.ToInt64(HttpContext.Current.Session["CompanyID"]));
            return userDashboardValues;
        }
        else
        {
            var viewConsultantDashboardCountValueBussinessLogicLayer =
                new ViewConsultantDashboardCountValueBLL();
            var consultantDashboardValues =
                viewConsultantDashboardCountValueBussinessLogicLayer.GetConsultantDashboardCountByUserId(Convert.ToInt64(HttpContext.Current.Session["LoggedUserId"]));
            return consultantDashboardValues;
        }
    }

Possible fix:

I removed the area where a problem could be. I now just have to go through my site to see if everything still works fine.

It seems to me like some of your resources are not available so they should be placed as emmbeded resource. Right click on file -> Properties -> Build Action -> Emmbeded Resource before you build your solution

and remove static if your web method is Static!
