Explicitly use a Func for asynchronous lambda function when Action overload is available

Question

Reading over this blog post on some of the gotchas of C#5\'s async/await. It mentions in Gotcha #4 something that is quite profound and that I hadn\'t thought of before.

Answer 1

There is a nice Roslyn analyzer from Microsoft team.

This analyzer helps prevent inadvertent creation of async void delegates.
