Editor's note
I curated a mixed issue this time: practical coding, platform basics, and a few productivity pieces. The chunking article and the PLINQ guide are good examples of everyday techniques that can still save real time in production code. I also liked the Swagger security and OpenTelemetry posts because they speak to the boring-but-important parts of shipping services.
