Want to execute queries Async on Azure Storage Client Version 4.0.1

There is NO method ExecuteQueryAsync()..

I am missing something? Should we continue to use the ExecuteQuerySegmentedAsync still? Thanks.

I end up making an extension method to use ExecuteQuerySegmentedAsync. I am not sure whether this solution is optimal, if anybody has any comment please don’t hesitate.

public static async Task<IList<T>> ExecuteQueryAsync<T>(this CloudTable table, TableQuery<T> query, CancellationToken ct = default(CancellationToken), Action<IList<T>> onProgress = null) where T : ITableEntity, new()
    {

        var items = new List<T>();
        TableContinuationToken token = null;

        do
        {

            TableQuerySegment<T> seg = await table.ExecuteQuerySegmentedAsync<T>(query, token);
            token = seg.ContinuationToken;
            items.AddRange(seg);
            if (onProgress != null) onProgress(items);

        } while (token != null && !ct.IsCancellationRequested);

        return items;
    }
