Editor's note
I pulled together another intentionally mixed issue today, which is how I like this newsletter best. The HybridCache guide stands out for its practical benchmarks and migration notes, while the IEnumerable vs IQueryable piece is the kind of production-focused reminder many teams need. I also liked the health checks article for pushing past the all-too-common “200 OK means healthy” assumption.
