 Libraries that may run in any process, whether they have a main thread or not, should code themselves defensively to avoid any dependency on the main thread so that applications that do not follow `JoinableTaskFactory` rules can avoid deadlocks even when synchronously blocking their main thread using `Task.Wait()` on code running inside your library.
 In particular, shared libraries of general interest should _always_ use `.ConfigureAwait(false)` when awaiting on tasks.
