Editor's note
I curated a fairly mixed issue this time, with infrastructure, data, language, and tooling pieces side by side. The Aspire and Azure Functions preview is one of the more practical platform updates, and the Azure SQL hybrid search post should be useful for anyone building modern discovery features. I also liked the EF Core testing standup and the GitHub Copilot MCP write-up for their hands-on, real-world angle.
