await AsyncMethod() versus await await Task.Factory.StartNew<TResult>(AsyncMethod)
===

Given the following method:

    public async Task<MyObject> DoSomethingAsync() {
        // do some work
        await OpenSomeFileAsync();
        return new MyObject();
    }

Is there a difference between:

    public async void SomeEventHandler(EventArgs args) {
        var myObject = await await Task.Factory.StartNew<Task<MyObject>>( DoSomethingAsync);
        // do something with myObject
    }

and:

    public async void SomeEventHandler(EventArgs args) {
        var myObject = await DoSomethingAsync();
        // do something with myObject
    }

I was thinking that the "do some work" part of DoSomethingAsync would happen immediately in a new task in the first case, but to be honest I don't really understand fully how Tasks, async and await are working, and I'm pretty sure I'm just overcomplicating things for myself.
