Home Archive Azure OpenAI, API Design, and EF Core Costs – .NET News Daily Issue #480 (Jun 22, 2026)

Editor's note

I kept this one deliberately mixed, which is usually where the best practical reading shows up. The .NET 10 REST API guide stands out for its production-minded coverage of versioning, caching, and Problem Details, while the EF Core Include() piece is the kind of performance warning many teams learn too late. There’s also a notable AI thread here, from Azure OpenAI support workflows to MCP integration and deployment on Azure.
