This time its all about ConfigureAwait, why we ended up having it and how it works under the hood!

But the idea of providing a synchronous facade on top of what is by nature an asynchronous operation seems like a hack, and very specific to the app model (UI vs background, etc.) - this is why ConfigureAwait and SynchronizationContext's are such a pain to manage within the library code itself.

Does it add .ConfigureAwait(false)?

How would it know not to do the implicit await/ConfigureAwait(false), like the following or in UI code?

The Kafka consumer will block the thread whilst it polls for work from the server.
You may well get away with it; provided nothing else queues to the thread that the background service is using.
Hence why you use ConfigureAwait(false) to force continuations onto the thread pool.

Stephen Cleary has a good article about the new ConfigureAwait options in .NET 8. Take a look:

Hmm, so I'd separate code into different files based on the need for ConfigureAwait(false)? Implicit and subtle.

I would separate UI code and service code.
What we can consider is, that you are allowed to add some explicit ".ConfigureAwait(...)" if you need it.
Of course "it depends" and will not fit everywhere. Hence the preprocessor directive.

Found this in our codebase:
var task = GetAsync();
task.ConfigureAwait(false);
task.ContinueWith(t => SomeStuff(t)).ConfigureAwait(false);
return task;
I'm not even mad. The more I see people using the TPL, the more I think ConfigureAwait was a mistake from an API perspective.

It's just that not all Task<T>-returning methods need to be async/awaited, and thus doesn't need ConfigureAwait.

I agree, I also like explicit-ness. For example I avoid default values for parameters. I prefer two overloads where the one with less args calls the other.
But all the "await" and ".ConfigureAwait(false)" are so... much. 😎
