Editor's note
I kept this issue deliberately mixed, which is usually where the most practical lessons show up. The HttpClient production failure piece and the Redis-backed distributed concurrency engine both get at the kind of reliability details that matter once systems are under load. I also liked the EF Core state machine article because it turns a common business workflow into something concrete and testable.
