Answer 1

ConfigureAwait(true) is the default and causes your Task to marshal back to the thread it was started at.

The deadlock is mostly caused by waiting on the result somewhere in the UI tread (wait, not await; by calling task.wait or task.result).

Your question cannot be answered without further context.
