Pushing 'await' to the Limits: Unleashing Multi-Threading Power in .NET
summary
Claims that awaiting can drive a fork‑join parallel loop by providing a custom task‑like type and a method builder that forks by shallow‑copying the generated state machine, stores per‑thread IDs in an AsyncLocal parallel context, and joins in IAsyncDisposable/IAsyncEnumerable disposal. Implements a parallel foreach as an extension (called something like AsParallelAsync), shows it runs correctly, measures comparable or faster times in a toy benchmark, and notes cancellation is not yet supported.
