Why this decision matters

Virtual Thread Incident Drill is focused practice for virtual thread operations. It explains why each answer is safe, risky, or production-ready.

Operate virtual threads, structured child tasks, scoped context, and pinning evidence.

Learning objectives

  • Retain resource guards when adopting virtual threads.
  • Own child-task lifetimes within request deadlines.
  • Diagnose carrier pinning from runtime evidence.
