Bringing smiles to the syntax — because laughter is the best error handler.
Learnings about .NET, JavaScript, Cloud, AI, and family.
Learn how to build a clean, production ready audit trail in EF Core that records who changed what and when without stuffing logic into your DbContext. We walk through a practical SaveChanges interceptor, compare it to overriding SaveChanges, and review trusted NuGet options. The post closes with performance and security practices that keep your database fast and your compliance officer calm.
Model validation has been a reliable but costly part of every ASP.NET Core request. In .NET 10 and C# 14, validation gets faster through precomputed metadata, typed execution, and fewer allocations. This post explains what changed under the hood, shows small runnable examples, and includes a micro-benchmark you can adapt. You will also see how to write lean custom validators and pair validation with faster JSON parsing. The end result is tighter p95 and p99 latency without rewriting your controllers.
Nullable<T> is not a mini reference type and pretending it is will bite you. This guide walks through how nullable value types work at runtime, how boxing really behaves, and what operator lifting does. You will see small, runnable C# snippets that expose common traps and safe patterns. Learn how to handle equality, pattern matching, and generics without surprises.
Join me for live coding sessions where I'm building Microsoft PowerToys. We laugh, we learn, and occasionally we break things spectacularly.
