C # Async Exception Wrapping

Question

I played with asynchronous calls in .NET 4.6.1, and I wonder what the correct way to throw errors is to implement an interface interface that expects an asynchronous method, but actually synchronous. For instance:

public interface ISomeInterface
{
    Task ExecuteAsync();
}

public class SomeClass : ISomeInterface
{
    public Task ExecuteAsync()
    {
        return Task.FromException(new Exception());
    }
}

I found Task.FromException here .

So this .NET 4.6 still seems to advise wrapping exceptions. However, I could just write the following code:

public class SomeClass : ISomeInterface
{
    public Task ExecuteAsync()
    {
        throw new Exception();
    }
}
