Hello!

Here's an example where TileFromItem always returns zero. 

Help please understand.

Hello,

It could return null in some scenarios where the tile is not yet generated. Can you please tell us on which event are you trying to get the Tile from item? If you are using this when a new item is added in the items source for example, you could also use Dispatcher.BeginInvoke to delay the execution async until the item is generated.
