Jasen's top three picks
- 1 ASP.NET Community Standup: Combining API Versioning with OpenAPI
youtube.com
The standup should help API teams line up versioned endpoints with clearer OpenAPI docs, and the Span versus Memory angle is a useful low-level refresher.
- 2 How to Implement Unit Testing in .NET using xUnit with Example
c-sharpcorner.com
A practical xUnit primer that fits newer .NET developers and teams trying to build better testing habits before bugs escape into production.
- 3 PostgreSQL Like a Pro: Build mission-critical apps at any scale with Azure HorizonDB

This one leans cloud and data platform, with useful context for scaling PostgreSQL on Azure and thinking through hosting choices for AI agents.
Editor's note
I pulled together another deliberately mixed issue today, from API versioning with OpenAPI to EF Core query behavior and a couple of practical AI agent pieces. The standup on versioning is worth your time if your APIs have grown beyond a single contract, and the EF Core translation article does a good job explaining why some LINQ never reaches SQL. There’s also solid nuts-and-bolts material here on xUnit, HttpClientFactory, and Azure Functions in containers.
