Uwp executes backgroundtask on user login

Question

I am learning win10 uwp and my goal is to perform an operation, for example, updating a tile when a user logs in.

I checked msdn and it seems like I need BackgroundTask. Therefore, I followed the instructions for creating and registering the background task found here https://msdn.microsoft.com/en-us/library/windows/apps/mt299100.aspx and on related pages.

BackgroundTaskBuilder taskBuilder= new BackgroundTaskBuilder();
taskBuilder.Name = "TaskClassName";
taskBuilder.TaskEntryPoint = "TaskNameSpace.TaskClassName";

// set conditions (execute when user become present)
taskBuilder.SetTrigger(new SystemTrigger(SystemTriggerType.SessionConnected, false));
taskBuilder.SetTrigger(new SystemTrigger(SystemTriggerType.UserPresent, false));

   var registration= taskBuilder.Register();

The namespace and my class BackgroundTaskare placed in a separate project under the same solution and added to the "Declaration" tab of Package.appxmanifest with the selected property System Event.

My implementation IBackgroundTask

    public void Run(IBackgroundTaskInstance taskInstance)
    {
        BackgroundTaskDeferral deferral = taskInstance.GetDeferral();

        UpdateMyTile();

        deferral.Complete();
    }

BackgroundTaskBuilder taskBuilderT= new BackgroundTaskBuilder();
taskBuilderT.Name = "TaskClassNameTimer";
taskBuilderT.TaskEntryPoint = "TaskNameSpace.TaskClassNameTimer";

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

var registration= taskBuilderT.Register();
