Using await for an async method.

No. That's not correct here, and will effectively jam your execution (I would say block your thread, but the async, threadless version of blocking a thread)

If you want to await it to get a result, you must do that after the execute, by storing the pending result in a local:

bar pending = tran.HashSetAsync(custKey, "UniqueID", newId);
bool committed = tran.Execute();
bar result = await pending;

I understand now, thanks!
