Home Archive Blob streaming, Git policy speed, API security – .NET News Daily Issue #445 (Apr 30, 2026)

Editor's note

I kept this one deliberately mixed, which is usually where the most useful issues land. The Azure Blob Storage piece is practical production guidance, and the Azure DevOps Git policy post stands out for showing concrete API-driven performance gains at scale. I also liked Damien Bod’s Entra External ID write-up because it addresses a very real abuse case teams can miss until costs show up.
