Missing .ConfigureAwait(false) calls on all awaits, causing deadlocks

[marc-costello]

As a library, unless you explicitly need to capture context, every await call should be followed by a ConfigureAwait(false).

Reason being, as a library author, you don't know how this is going to be consumed. For example, in our case, we are throwing the context away earlier on in the process by using .ConfigureAwait(false), prior to calling this library. In turn, this causes a deadlock when we call the async methods in this library, and tasks never complete. This effectively means that we can't use the asynchronous library calls 🤷‍♂️
