Redis locking, ASP.NET Core security, and EF Core testing
A varied .NET roundup with Redis concurrency, ASP.NET Core auth and JWT, EF Core testing, LINQ, architecture, and servicing updates.
Jasen's top three picks
- 1 How to support .NET Framework PDB format and source line with ISymUnmanagedReader
chnasarre.medium.com
Deep dive into legacy symbols and source mapping for folks still supporting .NET Framework.
- 2 Multiplexed RBAC in .NET — Part 2 : Distributed Rotational Cache with Redis & Lua
medium.com
Distributed Redis cache rotation with Lua and fallback handling is the sort of practical distributed-systems detail I like.
- 3 .NET and .NET Framework February 2026 servicing releases updates
devblogs.microsoft.com
The servicing update is the usual must-scan item if you ship on current .NET or Framework.
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.
