Windows Phone live tile WITHOUT plugins

How do we implement live tile in windows phone?
I have searched about it and found :

 UnityEngine.WSA.Tile liveTile = Tile.main;
 //then we update the tile with our latest high score
 //the first three strings are for images (medium,wide,large)
 //the last string is for text to display
 //you can also pass in an XML file to describe the tile
 liveTile.Update("","","", "Best round time: " + PlayerPrefs.GetInt("angka", 0));

But I can’t get it working?
is there anything else to change in visual studio project?

I got it working! Here’s a blog post about how to create a live tile in a Windows Phone 8.1 game without plugins.
