What’s new in .NET 8

Answer:

  • Enhanced background GC

  • Optional LOH compaction

  • Better adaptive heuristics

  • Support for sustained low-latency modes

❓Q7. What triggers Gen 0 vs Gen 2 collection?

TriggerGeneration
Gen 0 fullMinor GC
Gen 1 fullMedium GC
Gen 2 full or memory lowFull 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.
