Hello,

where I can display an alert to ask him,if sure he wants to exit.

If you want to detect the back icon clicked (triangle button), you can override OnBackButtonPressed method and push an alert. If user click the yes, we can execute Application.Current.Quit(); to finish application, if no, application still in the foreground and alert disappear.

   protected  override   bool OnBackButtonPressed()  
       {  
            
           Task<bool> answer =  DisplayAlert("Question?", "Do you want to exit?", "Yes", "No");  
           answer.ContinueWith(task =>  
           {  
              if (task.Result)  
               {  
                   Application.Current.Quit();  
               }  
           });         
           return true;  
       }
