title: Directly calling background task in UWP app
body: <p>I'm preparing for the new microsoft certification exam <a href="https://www.microsoft.com/en-us/learning/exam-70-355.aspx" rel="nofollow">Universal Windows Platform – App Data, Services, and Coding Patterns</a> </p>
  
  <p><strong>Is it possible to directly call background task from Windows 10 (Universal WIndows) app?</strong> As far as I know, only triggers like SystemTrigger or TimerTrigger can trigger the execution of background task</p>
  
  <p>In the skill mesuread section from the link is:</p>
  
  <blockquote>
    <h3>Implement background tasks</h3> 
    
    <p><p>Create a background task, register a background task, set and respond to triggers, debug a background task, implement a lock screen app, share data/events between an app and its background tasks; <strong>directly calling a background task</strong></P></p>
  </blockquote>
  
  <p>The last point, directly calling a background task, what does it mean?</p>
