Answer
Intern pool stores unique literals for lifetime of the process. Reduces duplication but increases memory pressure. Interning user input is dangerous due to unbounded growth.
Quick Answer
String interning stores one shared instance per unique string literal. string.Intern() can intern any string. Interned strings live in a process-wide pool and are never GC'd. Risk: interning dynamic strings (user input, random data) fills the intern pool permanently, causing memory growth that GC can't reclaim.
