Home Archive Redis locking, ASP.NET Core security, and EF Core testing – .NET News Daily Issue #392 (Feb 16, 2026)

Editor's note

I pulled together a fairly mixed issue this time, with deep internals, practical app guidance, and a couple of architecture pieces. The ISymUnmanagedReader article stands out for anyone dealing with old .NET Framework symbol and source-line support, and the Redis locking write-up is a nice look at safe shared-state updates under load.
