No, why would you? Just makes the processor waste time switching between things slowing down everything. It will not even start a new thread, just make the called code wait, instead of the caller.

An important thing to know is: Async/await is NOT concurrent programming. I will not start any new threads - it will not cause anything to be processed at the same time... only the method you call with an "await" can start work in parallel (by scheduling IO to complete on the IO completion threads, thread pool, it's own thread, or responding to events from other parts of the code potentially running on a different thread).

Sure, it can be used along with concurrency - and the way it is implemented can result in you running code concurrently that you did not expect - but that is a side effect and one of the things that makes async programming so hard.

Async on the server is not "invented to make the programmers life much easier". It is invented to get extra performance out of servers as they will waste less time context switching. It has been available for many many years (decades), but was horrible to program. Now we have async/await it is no longer horrible... just difficult. This is something you will notice as soon as you leave the safe path of demo applications.
