Are async handlers waited?

[bdongus]

I have the following event handler:

		public Task Handle(ProductCreated message, CancellationToken token = default) {
			if (message is not null) {
				_productUnitOfWork.ProductRepository.Add(new Product(message.Id, message.Name, message.Description));
				return _productUnitOfWork.SaveChangesAsync(token);
			}
			return Task.CompletedTask;
		}

My UI sometimes isn't updated. It seems your library isn't awaiting the returned Task. InvokeHandler in RouteRegistrar at least isn't.
Am I on the wrong path or is this something you can help me fixing it?

Hi. It's a bit hard to tell without seeing more of your code, I've tried reproducing your error but can't find any problems with async code and when I try to do something that takes time in a handler, its seems to be awaited. The RouteRegistrar-code is unfortunately very complex and its been 5 years or so since I touched it last, so its I don't have complete control at the moment, but can't trigger your bug. If you could make me a test or something similar that fails that would be greatly appreciated.
