Eu crio um rastreador que recebe as notícias de outro site que eu defini anteriormente para ele, então eu usoquartz para executar uma tarefa em segundo plano. o agendamento é definido assim:

public class JobBackground : IJob

        {

            public void Execute(IJobExecutionContext context)
            {
                for (int j = 1; j <= 920; j++)
                {


                    NewsRepository newsRepository = new NewsRepository();
                    GoyaAgent Goyaagent = new GoyaAgent();
                    Task<List<NewsContent>> lst = Goyaagent.parsing("http://www.gooyait.com/page/"+j);
                    List<NewsContent> enresult = lst.Result;
                    foreach (NewsContent newsContent in enresult)
                    {
                        News newnews = new News();
                        newnews.Subject = newsContent.Title;
                        newnews.NewsDate = DateTime.Now;
                        newnews.NewsBrief = newsContent.abs;
                        newnews.NewsText = newsContent.Content;
                        newnews.ShowOnSlide = "Yes";
                        newnews.GroupId = 1049;
                        newnews.NewsImageSmall = newsContent.Img;
                        newnews.NewsImageBig = newsContent.Img;
                        newnews.Reference = newsContent.Url;
                        newnews.UserId = "3";
                        newnews.Visible = "Yes";
                        newnews.ViewCounter = 0;
                        newsRepository.Add(newnews);
                        if (newsRepository.FindBy(i => i.Reference == newsContent.Url).Count() == 0)

                            newsRepository.Save();
                    }

                }
            }
        }

oparsing função:

 public async Task<List<NewsContent>> parsing(string newsArchive)
        {
            List<NewsContent> lstResult = new List<NewsContent>();

                try
                {
                    HttpClient http = new HttpClient();
                    var response = await http.GetByteArrayAsync(newsArchive);
                    String source = Encoding.GetEncoding("utf-8").GetString(response, 0, response.Length - 1);
                    source = WebUtility.HtmlDecode(source);
                    HtmlDocument resultat = new HtmlDocument();
                    resultat.LoadHtml(source);

                    List<HtmlNode> toftitle = resultat.DocumentNode.Descendants().Where
                        (x =>
                         (x.Name == "div" && x.Attributes["class"] != null &&
                          x.Attributes["class"].Value.Contains("main-col"))).ToList();
                    var li = toftitle[0].Descendants().Where
                        (x =>
                         (x.Name == "div" && x.Attributes["class"] != null &&
                          x.Attributes["class"].Value.Contains("base-box blog-post"))).ToList();

                    foreach (var item in li)
                    {
                        NewsContent newsContent = new NewsContent();
                        newsContent.Url = item.Descendants("a").ToList()[0].GetAttributeValue("href", null);
                        newsContent.Img = item.Descendants("img").ToList()[0].GetAttributeValue("src", null);
                        newsContent.Title = item.Descendants("h2").ToList()[0].InnerText;
                        newsContent.abs = item.Descendants("p").ToList()[0].InnerText;
                        //finding main news content
                        var response1 = await http.GetByteArrayAsync(newsContent.Url);
                        String source1 = Encoding.GetEncoding("utf-8").GetString(response1, 0, response1.Length - 1);
                        source1 = WebUtility.HtmlDecode(source1);
                        HtmlDocument resultat1 = new HtmlDocument();
                        resultat1.LoadHtml(source1);
                        HtmlNode doc = resultat1.DocumentNode.SelectSingleNode("//div[@class='entry-content']");
                        HtmlNode node = doc.SelectSingleNode("//div[@class='yasr-visitor-votes']");
                        if (node != null)
                            node.ParentNode.RemoveChild(node);
                        HtmlNode node1 = doc.SelectSingleNode("//div[@class='post-tags']");
                        if (node1 != null)
                            node1.ParentNode.RemoveChild(node1);
                        HtmlNode node2 =
                            doc.SelectSingleNode("//div[@class='mom-social-share ss-horizontal border-box']");
                        if (node2 != null)

                            node2.ParentNode.RemoveChild(node2);
                        HtmlNode node3 = doc.SelectSingleNode("//script|//style");
                        if (node3 != null)

                            node3.ParentNode.RemoveChild(node3);

                        newsContent.Content = doc.InnerHtml;



                        lstResult.Add(newsContent);


                    }
                }
                catch (Exception e)
                {

                }
                return lstResult;
        }

A programação começa com este código:

  public class JobScheduler
        {
            public static void Start()
            {
                IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();
                scheduler.Start();

                IJobDetail job = JobBuilder.Create<JobBackground>().Build();

                ITrigger trigger = TriggerBuilder.Create().StartNow()
                    .WithDailyTimeIntervalSchedule
                      (s =>
                         s.WithIntervalInHours(24)
                        .OnEveryDay()
                        .StartingDailyAt(TimeOfDay.HourAndMinuteOfDay(0, 0))
                      )
                    .Build();

                scheduler.ScheduleJob(job, trigger);
            }
        }

Existem vários problemas:

Quando executo esse código, o código nunca é executado por causa deITrigger trigger = TriggerBuilder.Create().StartNow() então eu tenho que esperar 24 horas para ver o resultado por quê?

E o segundo problema, quando carrego o código no servidor web, ele não funciona. Por que?
