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.
Let's break down the real jobs of typeof, object.GetType and Type.IsAssignableFrom with small, runnable examples and a few nerdy references for fun. You will learn when to reach for each API, why EF Core and infrastructure code lean on assignability checks, and how pattern matching fits into the story. We will cover null pitfalls, open generic comparisons and proxy types. By the end, your type checks will read clearly and behave predictably.
Tired of arguing about repositories in EF Core? This practical guide compares direct DbContext, thin repositories, and specification style queries with small, runnable C# examples. Learn when each option shines, what to avoid, and how to keep your code clean without hiding EF Core features. We also cover testing pitfalls and safer alternatives. Leave with a simple decision map you can apply to your next .NET project.
