I am trying to save my layout but all I get back is this... I have three tiles inside the control.
<?xml version="1.0" encoding="utf-8"?><xamTilesControl assemblyVersion="10.1.20101.2216" layoutVersion="1" isExplicitLayout="true"> <items /></xamTilesControl>
I figured it out. I wasn't using the SerializationId which is required to make the layout save work.
