CLR internals, auth, EF Core
A varied .NET roundup covering runtime internals, Keycloak auth, SQL client migration, EF Core patterns, MAUI, and local AI scripting.
Jasen's top three picks
- 1 Common Language Runtime (CLR) in .NET
C# Corner
A refresher on CLR basics and how the runtime fits together.
- 2 Implement ASP.NET Core OpenID Connect with Keycloak to implement Level of Authentication (LoA) requirements
Software Engineering
A practical walkthrough for higher-assurance OpenID Connect flows with Keycloak.
- 3 Why You Must Switch from System.Data.SqlClient to Microsoft.Data.SqlClient Now
Medium
Worth the switch reminder if you're still on the old SQL client package.
Editor's note
I curated a mixed issue this time, with runtime, data, auth, and AI pieces all in the same lineup. The CLR overview is a solid refresher, and the Keycloak/OpenID Connect article is especially useful for teams that need LoA-aware login flows. I also liked the SQL client migration note for its practical urgency, alongside the MAUI and local AI posts that point to where the platform is headed.
