Records, pattern matching, ref struct, ValueTask, and primary constructors — how they change production code in 2026.
Inheritance chains break the Liskov Substitution Principle in practice. Here is how to refactor a 3-level hierarchy into composable behaviour with C# interfaces and DI.
Minimal APIs are not just for tiny services. Here is the production trade-off matrix and how to scale them without losing structure.
Detect, profile, and fix the N+1 query problem in EF Core. With AsNoTracking, split queries, and the explicit-loading patterns you should know.
Practical LINQ recipes that solve real problems: grouping with lookups, pivoting, window functions, and when to drop down to raw SQL.
SOLID is a heuristic, not a checklist. Real-world examples of when each principle helps — and the specific cases where applying it hurts.
Strategy, Decorator, Adapter, Builder, and Mediator — with the C# idioms that make them feel natural rather than ceremonial.
A real production debugging story: the systematic path from "the dashboard is slow" to a 25x speedup. Tools, traces, and the four bottlenecks we found.
Microservices solve specific problems. Adopting them without the prerequisites doubles your operational cost and slows delivery. Here is when to say no.
