The async Operator — C#'s Biggest Mistake?
summary
This talk examines problems with C#'s async/await model and argues that widespread reliance on the async operator is misguided. It covers issues observed in real implementations—global state interactions, exception handling, deadlocks, and garbage-collection impacts—and critiques the design choices behind the async mechanism rather than offering simple usage guidance.
