How to implement Async Command

Question

Although I have understood async programming with c# somehow, still don\'t get why async with void is not the better solution, then when I want to improve my Xamarin Forms code

Answer 1

There is nothing wrong with async void on a command execute handler providing you handle your exceptions.

So what does an AsyncCommand, offer? Potentially the following

• An error channel to pass back any unhandled exceptions

• Not having to write async void or async lamdas

• IsBusy framework, to stop things like double hits or what ever you can imagine
