Player A gets the ball and just does a routine lay-up at the opponent's basket, unbeknownst to him/her that's not their basket and it goes in - no foul, no anything.

You're wiping it and calling it a violation because you can't have a try at the wrong basket?

That's not it. It doesn't have to be a try to score. But a foul does not cause the ball to become dead if a try is in flight. In your situation, the foul causes the ball to be dead immediately.
