| Await<T>(IEnumerable<Task<T>>) | Creates a sequence query that streams the result of each task in the source sequence as it completes asynchronously. |
| Await<T, TResult>(IEnumerable<T>, Func<T, CancellationToken, Task<TResult>>) | Creates a sequence query that streams the result of each task in the source sequence as it completes asynchronously. A CancellationToken is passed for each asynchronous evaluation to abort any asynchronous operations in flight if the sequence is not fully iterated. |
