Is there any way to understand that the currently displayed main tile was pushed (updated) from server side?
The reason I'm asking: my app can update tile image from background agent and I want to have pushed tile image unchanged until user opened the application.
PS. I used reflector to understand tiles implementation but have not found anything I can potentially use (time stamp, any image information, no other IDs).
EDIT
I found out that the pushed tile image is stored as png at Applications\Data{appguid}\Data\ShellContent system folder. Isolated storage root folder is Applications\Data{appguid}\Data\IsolatedStore. So I tried to access to this folder from iso root directory using "..\ShellContent", but got Operation Not Permitted exception. The "..\IsolatedStore" works.
