Editor's note
I pulled together a mixed issue again, with no single theme by design. The MAUI 16 KB page-size prep piece is especially timely for teams shipping Android apps, and the background services article is a good reminder that hosted code can fail quietly in production. I also liked the C# 14 extension members write-up because it points at language changes many teams will soon want to experiment with.
