At the moment I want to register a background task. Here is the registration code:

private void RegisterBackgroundTask() { var exampleTaskName = "BackgroundTaskForMedia"; foreach (var task in BackgroundTaskRegistration.AllTasks) { if (task.Value.Name == exampleTaskName) { Debug.WriteLine("Unregister"); task.Value.Unregister(true); break; } } BackgroundTaskBuilder taskBuilder = new BackgroundTaskBuilder(); taskBuilder.Name = taskName; taskBuilder.TaskEntryPoint = taskEntryPoint; taskBuilder.SetTrigger(new TimeTrigger(15,false)); var registration = taskBuilder.Register(); }

And here is the code of this background task (purely an example that would just understand whether it works or not):

  public async void Run(IBackgroundTaskInstance taskInstance) { _deferral = taskInstance.GetDeferral(); Debug.WriteLine("In BackgroundTaskForMedia.Run"); await Open(); _deferral.Complete(); } private async Task Open() { await Launcher.LaunchUriAsync(_uri); }

So, when you start the application, this task appears to be registered, because after a new call to the registration code, a message is displayed on the console to deregister.

However, the task itself is not executed. A new page in the browser does not open, nothing new on the Debug panel. What's wrong?

    It worked when I changed it:

     taskBuilder.SetTrigger(new TimeTrigger(15,false));

    On this:

     taskBuilder.SetTrigger(new SystemTrigger(SystemTriggerType.NetworkStateChange, false));

    Phah, it turns out everything worked before. Today I turned on the computer and I received a notification about the work of the task (and I did not include the application). Now you just need to remove all these tasks.
