Answer
- Reflection: runtime inspection, slow
- Emit: dynamic IL generation
- Expression Trees: compile to delegates for fast execution
- Source Generators: compile-time code generation using Roslyn
Quick Answer
Reflection: runtime type inspection and invocation — slow, bypasses compile-time safety. Reflection.Emit: generates IL at runtime — used in proxies and ORMs. Expression Trees: represent code as data structures, compiled to delegates — used in LINQ providers. Source Generators: generate code at compile time — zero runtime cost, the modern preferred approach.
