Override th ImageTiledLayer in version 100.1

In January I asked for overloading ImageTiledLayer in WPF API v 100.0. In summary  

with same tile info ImageTiledLayer.GetTileDataAsync is never invoked, but ServiceImageTiledLayer.GetTileUriAsync is invoked correctly.  The result was that I used ServiceImageTiledLayer.

In release notes for version 100.1 is:

"Also, custom tiled layers can be created by sub-classing ImageTiledLayer and its subclass, ServiceImageTiledLayer. These two abstract classes expose protected abstract methods to either fetch tile images or return the URL of the tile images".

So I tried use ImageTiledLayer, but GetTileDataAsync is never called.


Can you please provide an example with functional overriding of ImageTiledLayer?
