Concrete expansion Bolts

I am having a concrete foundation poured on which I will install a prefab shed. It will be anchored to the concrete via expansion bolts. How long should I let the concrete cure before drilling?

28 days is the norm for allowing concrete to cure

Why not set concrete anchor bolts into the wet concrete?
