In case you didn’t realize it by now, up until today the Windows Store had been filled with free consumer previews of apps. Today the switch was turned on for Paid App submissions. That means developers can start monetizing their apps. Company accounts can submit apps too.

Ted Dworkin, Partner Program Manager for the Store, authored this post.
