Multiple async/await chaining

Question

How to make multiple async/await chaining in C#? For example, start few HTTP requests and then do not wait all of them, but start new request after each completed?<

Answer 1

The easiest way to do this is to write an async method:

async Task DownloadAndFollowupAsync(...)
{
  await DownloadAsync();
  await FollowupAsync();
}

Which you can then use with await Task.WhenAll:

await Task.WhenAll(DownloadAndFollowupAsync(...),
    DownloadAndFollowupAsync(...));
