Home Archive MCP, Claude Code, and .NET patterns – .NET News Daily Issue #453 (May 12, 2026)

Editor's note

I pulled together another deliberately mixed issue today, with a lot of AI tooling sitting alongside classic architecture and design material. The MCP article stood out because it gets concrete about replacing custom integration glue in .NET, and the .NET 10 chiseled container write-up is a useful real-world look at tightening deployment footprints. There’s also a solid spread of pattern content here, from repository to observer, plus a few developer workflow pieces worth comparing.
