EF Core Concurrency, Agents, and Span
Covers EF Core 10 optimistic concurrency, durable Microsoft Agent Framework workflows, .NET 9 memory primitives, MAUI UI, and VS Code tooling.
Jasen's top three picks
- 1 Working with Span, Memory, and ref structs in High-Performance Apps using .NET 9
c-sharpcorner.com
A practical refresher on the allocation-free toolbox in .NET 9, with the right focus on GC pressure and when stack-backed types actually help.
- 2 Why not have changes in API behavior depend on the SDK you link against?
devblogs.microsoft.com
Classic Raymond Chen: a sharp reminder that API behavior tied to linked SDKs creates compatibility traps you really do not want.
- 3 Modernising a Legacy Fleet Platform: Architectural Decisions, Scope Uncertainty, and a Phased Path…

Good architectural write-up on modernization trade-offs, especially the phased path when scope is still moving under your feet.
Editor's note
I pulled together another deliberately mixed issue today, from low-level .NET 9 memory work with Span, Memory, and ref structs to pragmatic EF Core 10 concurrency handling in Web API. The Durable Workflows post for Microsoft Agent Framework also stood out because it shows where agent orchestration is getting concrete, while the BackgroundService behavior change in .NET 11 is the kind of runtime detail that can save debugging hours.
