Await or forget about it Any async method that returns a Task or Task<T>, you should always await the result. If you do not await, any exceptions that occur in the calling method will be swallowed.  Essentially you are turning the method call into a fire and forget. Async Await Exceptions Example Below is a simple example that… Read More »Handling Async Await Exceptions
