title: Toast notifications only pop up if the app is being activated
body: <p>I have this problem with toast notifications, my app shows toast notifications only when it is activated (I.e: when I am using it).</p>
  
  <p>Here is my code for the toast notifications:</p>
  
  <pre><code>    private void ShowToastNotification(string text)
      {
          var xml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText01);
  
          xml.GetElementsByTagName("text")[0].AppendChild(xml.CreateTextNode(text));
  
          ToastNotificationManager.CreateToastNotifier().Show(new ToastNotification(xml));
      }
  </code></pre>
  
  <p>My application is simply a reminder application, user set time and text and when it is time the app will show toast notification for that text.
  I simply use a looped timer that checks for reminders each 5 seconds.</p>
  
  <pre><code>    public MainPage()
      {
          this.InitializeComponent();
  
          DispatcherTimer d = new DispatcherTimer();
          d.Interval = new TimeSpan(0,0,5);
          d.Start();
          d.Tick += delegate
          {
              CHECK();
          };
      }
  
      private void CHECK()
      {
          foreach (REMINDER_CLASS er in REMINDERS)
          {
              if (DateTime.Now.ToString("MM/dd/yyyy hh:mm:tt") == er.DateTime)
              {
                  ShowToastNotification(er.Reminder);
  
                  break;
              }
          }
      }
  </code></pre>
  
  <p>So when time comes it does not show the toast notification and when I click on the application it shows the notification, it is like it was suspended and when I opened it it resumed.</p>
  
  <p>By the way I have Toast capable set to yes in my appxmanifest and also added BackGround Tasks of type: Timer and System Event inside my Declarations.</p>
  
  <p>The solution could be not allowing the app to sleep or suspend but I don't know how to stop the app from suspending.
  And the other solution could be BackGround Tasks and I would be thankful if you gave me a good simple resource for background tasks.</p>
