EF Core Tuning, ASP.NET Core AI, Azure DevOps
Coverage spans EF Core performance, vertical slice architecture, Azure DevOps APIs, testing, exception handling, MAUI, and practical AI patterns.
Jasen's top three picks
- 1 Optimizing Entity Framework Core Queries for Large-Scale Applications
c-sharpcorner.com
Solid refresher on the usual EF Core hotspots: projection, tracking, pagination, and indexes still move the needle first.
- 2 Vertical Slice Architecture in C# (.NET 8): A Complete Guide with Production-Ready Examples
medium.com
If you like feature-first organization, this is a good production-minded vertical slice walkthrough with familiar CQRS and MediatR tradeoffs.
- 3 Get Service Connections with the Azure DevOps API (REST and TypeScript)
johnnyreilly.com
Useful nuts-and-bolts Azure DevOps API post. I appreciate seeing both curl and TypeScript instead of a hand-wavy overview.
Editor's note
I kept this one deliberately mixed, which is how I like these issues. The EF Core query tuning piece is useful for teams feeling database pain in production, and the Azure DevOps service connections article is the kind of practical API walkthrough that saves real time. I also liked the snapshot testing guide because it focuses on a technique plenty of .NET teams still underuse.
