- This question tests whether a developer has worked with multi threading. This is usually a good indicator for experience that a developer has written applications more complicated that run of the mill.
Potential Answers:
Async and await are language keywords that generate intermediate language that will free up the current thread for long running awaited calls. This is typically used for scenarios where a thread may make out of process calls and may be tied waiting for a response for example when you call a database or a service. Modern infrastructure is multi cored and this allows for more effective utilization of computing resources improving overall system performance.
