Question

Good Day All

i have an app with similar functionality as Twitter and Facebook. in the app a user can like a post . which means when a user tabs the like button , it will update on the db that this post has been liked by User X and the increase of likes will show e.g Likes 1.

Now my here is my scenario

User X likes a post from [device 1]

and User X2 must be able to see the likes increase from [device 2]

Hello,​

Welcome to our Microsoft Q&A platform!

You can request data from DB with device timer or Task like following code, then refresh data in the view.

   Device.StartTimer(TimeSpan.FromMinutes(1), () =>  
   {  
      var shouldTimerContinueWork = true;  
      /*your code*/  
      return shouldTimerContinueWork;  
   });  


   System.Threading.Tasks.Task.Run(() =>  
    {  
         //Add your code here.  
    }).ConfigureAwait(false);
