The Perils of Native Resource Management in .NET: A Tale of Unexpected GC Behavior

This post delves into the potential pitfalls of native resource management in .NET. The author uses a RocksDB example to illustrate how unexpected garbage collection behavior can lead to native resources being released before use, resulting in crashes. The root cause lies in the fact that local variables and instances can be garbage collected during a method call. The article ultimately advocates for using SafeHandle to manage native resources safely, preventing these hard-to-reproduce Heisenbugs.
