Hello,

I get this message, but I don’t understand what it means.  
I use GenerateTileCacheAsync, but instead I need to use GenerateTileCacheAsync (the same ??)

Or am I performing GenerateTileCacheAsync on LayerOverlay and now it has to be executed on Layer?  
But I have multiple layers in an overlay, then do I have to call this function for each layer?

Please explain to me, what I need to do.

Kind regards,  
Guido van den Boom

Hi Guido,

It’s a static method, you only need to run it once and pass in multiple layers to it.

This method was in LayerOverlay (which is only available in Desktop Edition), we moved it over to Layer so it can be used in other platforms.

Thanks,  
Ben
