Use ConfigureAwait(false) in a Windows Service?

Question

As far as I know, there isn't a synchronization context in a Windows Service application.

• Does await fooTask.ConfigureAwait(false) give me any benefits in Windows Services?
• Are there any pitfalls to this?

There is no pitfalls, for as long as there is no code which would install a synchronization context. There is no benefits either, for as long as this code runs on a thread without synchronization context. It still makes sense for a shared class library. – Lochia

@Noseratio Why don't you post that as an answer? – Niu

There is no pitfalls, for as long as there is no code which would install a synchronization context. There is no benefits either, for as long as this code runs on a thread without synchronization context.

Nevertheless, this code still would make sense for a shared class library, aimed to be used in different execution environments.

If you did have a synchronization context, there might be some pitfalls.

Updated: it's now 2021 and here's what I think about using ConfigureAwait these days.
