yield.Break() leads to TaskCanceledException

[Denis535]

Look at next code:

    var e = GetItems().GetAsyncEnumeratorAsync().Result;
    e.MoveNextAsync().Wait();
    e.MoveNextAsync().Wait(); // this line throws: TaskCanceledException: A task was canceled.


    private static IAsyncEnumerable<int> GetItems() {
        return new AsyncEnumerable<int>( GetItems );
    }

    private static async Task GetItems(AsyncEnumerator<int>.Yield yield) {
        await Task.Delay( 1 );
        await yield.ReturnAsync( 0 );

        yield.Break(); // break

        await Task.Delay( 1 );
        await yield.ReturnAsync( 1 );
    }

IEnumerable.MoveNext() returns just false when enumerator is ended with yeild. So I decided it's bug or strange behavior.

IAsyncEnumerable.ForEachAsync( ... ).Wait() also leads to exception. And it's real problem.

@deni35, yes, it's a bug indeed. The problem has been fixed and the new version 2.2.2 is available here:
