6 Hidden C# Features Every Unity Developer Should Know

Hidden features of C# can dramatically improve your Unity development workflow, and in this video we explore a curated set of underused but powerful language capabilities—from default interface methods and `CallerMemberName` for intelligent logging, to custom numeric formatting and lazy iteration with `yield return`. We demonstrate how implicit and explicit operators add type safety to game-specific structs like `Health`, and how LINQ's deferred execution affects performance and logging behavior. You’ll also see how to slice arrays using index and range operators, and how to build concise, readable, and efficient code without compromising control. Whether you're a Unity developer looking to sharpen your C# skills or just curious about features hiding in plain sight, this walkthrough offers practical examples you can drop directly into your projects.
