Using GC.KeepAlive in async methods

This technical article analyzes a C# code snippet where a delegate is prematurely garbage collected despite using GC.KeepAlive in an async method. It delves into how the garbage collector tracks object lifetimes, the special challenges with native method interop, and why the common safeguard can fail in asynchronous contexts. The post is based on a real issue from the dotnet/runtime repository.
