How can I update my tiles in the background while my app is not running in the foreground? I tried looking into push notifications, but I don’t think that’ll get me anywhere.
Where to begin? I know how to create tiles already.

An app cannot update it’s tile without running at least once. Because apps do not run immediately on installation, it isn’t possible for a tile to be “live” until it is launched. After app installation, the user needs to launch the app for it to set up and begin receiving updates in any form (whether they are push notifications, periodic updates, scheduled notifications, or local notifications raised with or without a background task). The default tile will be shown from the point the user installs the app until the time the app sets up tile updates.
MSDN has a good article on choosing the right notification delivery mechanism, which also links to related code samples:
