What triggers Gen 0 vs Gen 2 collection?

Trigger	Generation
Gen 0 full	Minor GC
Gen 1 full	Medium GC
Gen 2 full or memory low	Full GC

🏁 Final Thoughts

• Gen 0: For short-lived objects → collected frequently

• Gen 1: For medium-lived → collected occasionally

• Gen 2: For long-lived → collected rarely

The CLR GC algorithm is a mark-sweep-compact generational collector — highly optimized for real-world workloads.

In .NET 8+, it’s so smart that manual memory management is almost never required — just follow clean object lifetime practices, and GC will handle the rest.
