how to handle if asyn process returns before await?
If GetStringAsync (and therefore getStringTask) completes before GetUrlContentLengthAsync awaits it, control remains in GetUrlContentLengthAsync. The expense of suspending and then returning to GetUrlContentLengthAsync would be wasted if the called asynchronous process getStringTask has already completed and GetUrlContentLengthAsync doesn't have to wait for the final result.

Use
ConfigureAwait(false)When AppropriateIn library code or non-UI contexts, you might write:
string content = await getStringTask.ConfigureAwait(false);
This avoids capturing the synchronization context, which can further reduce overhead — especially in ASP.NET or background services.
