Robust and efficient library for management of asynchronous operations.

  • Allocation-free async operations
  • Cancelable operations with custom allocation-free CancelationToken/Source
  • Allocation-free async iterators with async Linq
  • Progress with enforced normalization
  • async/await support and .Then API
  • Thread safe
  • Full causality traces
  • Easily switch to foreground or background context
  • Combine async operations
  • Circular await detection
  • Interoperable with Tasks
  • CLS compliant

This library was built to work in all C#/.Net ecosystems, including Unity, Mono, .Net Framework, .Net Core, and AOT compilation. It is CLS compliant, so it works with any .Net language.

ProtoPromise conforms to the Promises/A+ Spec as far as is possible with C#.

Fixes:

- Fixed `Promise.ParallelFor*` canceling workers too early.
- `Promise.ParallelFor*` and `AsyncEnumerable.Merge` propagate exceptions from cancelation token callbacks instead of deadlocking.

Misc:

- `AsyncEnumerable.Merge` more eagerly stops iteration if a rejection or cancelation occurs.
