Video Description
Memory management used to be a nightmare - now C# handles it for you! Let's understand how garbage collection works and why you can stop worrying about memory leaks.
What you'll learn: • What garbage collection is (your automatic memory recycler) • Manual vs automatic memory management • Why C# developers sleep better than C developers • When the garbage collector runs (spoiler: you don't control it) • The generations concept - how GC organizes objects by age • Common GC myths debunked • Why you shouldn't call GC.Collect() • Memory pressure and automatic cleanup
Key insights:
• The GC watches your program and jumps in when needed
• Objects are organized by likelihood of becoming garbage
• Gen 0: Short-lived objects (collected frequently)
• Gen 1: Survived one collection (collected less often)
• Gen 2: Long-lived objects (collected rarely)
Myths we'll bust: • "Setting variables to null helps" (it doesn't) • "Calling GC.Collect() is good" (please don't) • "GC is slow" (modern GC takes microseconds) • "GC causes memory leaks" (it prevents them!)
