Source Generators

Reflection inspects your code at runtime: it walks types, reads attributes, and builds delegates on the fly. Source generators do the same kind of work, but at compile time, by writing extra C# files into your build before it produces an assembly. This lesson covers what source generators are, the incremental generator pipeline, and a small worked example that emits a ToString() override from a [ToString] attribute. The payoff is the same boilerplate you'd write by hand or fish out with reflection, with zero runtime cost and full compatibility with NativeAOT and trimming.
