How I understood ConfigureAwait

1. ConfigureAwait works in places where there is a synchronization context.
2. await breaks the code into two parts using a state machine and the second part (continuation) is posted to the Post method of the synchronization context.
3. Having your own synchronization context, you can control where to invoke the continuation.
4. This example puts the continuations to a queue and has a worker that dequeues continuations and invokes them.
5. The worker runs on the main thread.
6. Having ConfigureAwait(true) tells the program to use the same synchronization context for the continuation.
7. If set to ConfigureAwait(false) the synchronization context will not be used.
