I apologize to everyone who’s waiting for my response to their code review requests. I was busy dealing with some personal stuff the last couple of weeks. Moving forward, I’m going to maintain a one post a week schedule where "regular" articles would take turns with code reviews. This article is a regular one, so the one next week would be a code review.

Today, I’d like to talk about IEnumerable and IReadOnlyList collection interfaces. We’ll discuss which of them is preferable and in what circumstance.
