Kubernetes 1.22 removed multiple v1beta1 APIs that had been deprecated since 1.16. If your cluster upgraded without deploying updated manifests, things likely broke. Key Removals Old API New API extensions/v1beta1 Ingress networking.k8s.io/v1 Ingress rbac.authorization.k8s.io/v1beta1 rbac.authorization.k8s.io/v1 admissionregistration.k8s.io/v1beta1 admissionregistration.k8s.io/v1 How to Detect Key Takeaways Use **kubent** (kube no trouble) to scan for deprecated APIs before upgrading. Always […]

Designing for Nullability in C#
With Nullable Reference Types (NRTs) enabled by default in .NET 6 templates, designing APIs that clearly communicate nullability is no longer optional—it’s expected. Enabling NRTs Guard Clauses Use the new .NET 6 helper to throw if null. Key Takeaways Use `string?` to explicitly mark nullable strings. Use `!` (null-forgiving operator) sparingly—only when you truly know […]

Minimal APIs are the biggest shift in ASP.NET Core since version 1.0. They remove the MVC ceremony (Controllers, Actions, Filters) in favor of a fluent lambda-based syntax. The Code Is it just for tiny apps? No. Performance is technically better than MVC (fewer allocations, no Filter Pipeline overhead). However, organization becomes the challenge. You don’t […]

Supports the full OAuth2/OIDC test suite.

Azure Container Apps (ACA) is the “Serverless Containers” offering we’ve been waiting for. Built on Kubernetes but hiding the cluster, it integrates **KEDA** (for event-driven scaling) and **Dapr** (for building blocks) natively. Scaling to Zero Unlike App Service, ACA can scale to 0 replicas when no events are processing, saving money. Dapr Integration Enable Dapr […]
