Home Archive Async internals, Dapper, Azure blobs – .NET News Daily Issue #430 (Apr 9, 2026)

Editor's note

I kept this one deliberately mixed, which usually makes for a better daily read. The async/await pair stands out because one explains the mechanics while the other steps back and looks at the concurrency mindset shift. I also liked the Dapper connection pooling piece and the captive dependency guide since both hit problems that show up quickly in real production apps.
