следует также отметить, что ошибки, которые не устанавливают код ошибки http 500

(например, UnauthorizedAccessException)

не будет обрабатываться фильтром HandleError.

атрибуты в MVC очень полезны при обработке ошибок в получить и отправить метод, он также трек для ajax call.

создайте базовый контроллер в своем приложении и унаследуйте его в своем главном контроллере(EmployeeController).

public class EmployeeController: BaseController

добавить ниже код в базу контроллер.

ошибка отслеживания AJAX:

вызов функции CheckAJAXError при загрузке страницы макета.

function CheckAJAXError() {
    $(document).ajaxError(function (event, jqXHR, ajaxSettings, thrownError) {

        var ex;
        if (String(thrownError).toUpperCase() == "LOGIN") {
            var url = '@Url.Action("Login", "Login")';
            window.location = url;
        }
        else if (String(jqXHR.responseText).toUpperCase().indexOf("THE DELETE STATEMENT CONFLICTED WITH THE REFERENCE CONSTRAINT") >= 0) {

            toastr.error('ReferanceExistMessage');
        }
        else if (String(thrownError).toUpperCase() == "INTERNAL SERVER ERROR") {
            ex = ajaxSettings.url;

решение для кода ошибки http до 500 это атрибут под названием [ERROR] put it on an action

public class Error: System.Web.Mvc.HandleErrorAttribute
{
    public override void OnException(System.Web.Mvc.ExceptionContext filterContext)
    {

            if (filterContext.HttpContext.IsCustomErrorEnabled)
            {
                filterContext.ExceptionHandled = true;

            }
            base.OnException(filterContext);
            //OVERRIDE THE 500 ERROR  
           filterContext.HttpContext.Response.StatusCode = 200;
    }

    private static void RaiseErrorSignal(Exception e)
    {
        var context = HttpContext.Current;
      // using.Elmah.ErrorSignal.FromContext(context).Raise(e, context);
    } 

}

//пример:

[Error]
[HandleError]
[PopulateSiteMap(SiteMapName="Mifel1", ViewDataKey="Mifel1")]
public class ApplicationController : Controller
{
}

У вас отсутствует ошибка.aspx:) в preview 5 это находится в вашей папке Views/Shared. Просто скопируйте его из нового проекта Preview 5.
