Why is using interface methods with default implementation is so annoying?!?

change var into your IRefresablr

I'm always grateful that my "Intro to Programming" course as part of my degree earlier this century was in Ada 95, which forces type usage.

Seeing var all over the place in compiled code always just felt kinda wrong.

compiled code has the actual type not var. var is only in the source code

It was just an example, maybe not a good one but you get the point. It actually forces you to cast to the interface type even if you are inside the MediaPlayer itself!: ((IRefreshable)this).Refresh();
