async/await - when to return a Task vs void?

Question

Under what scenarios would one want to use

public async Task AsyncMethod(int num)

instead of

public async void AsyncMetho         


        

Answer 1

My answer is simple you can not await void method

Error   CS4008  Cannot await 'void' TestAsync   e:\test\TestAsync\TestAsyncProgram.cs

So if the method is async it is better to be awaitable, because you can loose async advantage.
