摘要： A system that manages lifetime of an object is provided. The system analyzes references on multiple objects to determine reachability of a native peer and dynamically transitions between native and managed object lifetime management systems based on the analysis. When a native peer is not reachable by a native application reference, the system weakens references to a managed peer avoiding memory leaks and clones the native references to the managed side to avoid premature collection. The system performs an optimized cleanup during object system shutdown wherein the references between managed and native peers are released and SafeHandles are suppressed from finalization. The system employs a pending remove list that stores a reference to a weak reference of a managed peer to eliminate race conditions that occur during finalization.
