Is there a way to await async operations inside of `.Select(...)`, `.CrossApply(...)`, `.Do(...)`?

^{Originally posted by eisbaer66 August 21, 2022} Can is use async/await inside of .Select(...), .CrossApply(...), .Do(...)? Do i have to call .Result/.Wait() myself? Is this safe?

for example calling a REST api and reading the content as string:

stream.Select("get content", async context => await context.httpClient.GetStringAsync(context.url));
```</div>

something will be developed for rest api. For now, the workaround is here: https://github.com/paillave/Etl.Net/discussions/378
