Editor's note
I curated a pretty wide mix this time, from old-school Windows compatibility internals to newer .NET 10 and Aspire talk. The EF Core repository critique and the MediatR parallel notifications piece stood out because they challenge habits many of us have used for years. I also liked the Redis caching and rate limiting articles for the practical production angle.
