Answer
- Reflection: slow metadata inspection.
- Reflection.Emit: runtime IL generation.
- Expression Trees: build code graphs; compile to delegates.
- Source Generators: compile-time code generation.
Quick Answer
Reflection: slow runtime inspection, good for general-purpose tools. Reflection.Emit: generates IL at runtime, used in ORMs and proxies. Expression Trees: build code as data structures, compile to delegates, used in LINQ providers. Source Generators: generate code at compile time — zero runtime cost, the modern preferred approach.
