Correct way to get the CoreDispatcher in a Windows Store app

I'm building a Windows Store app, and I have some code that needs to be posted to the UI thread.

For that, i'd like to retrieve the CoreDispatcher and use it to post the code.

It seems that there are a few ways to do so:

// First way
Windows.ApplicationModel.Core.CoreApplication.GetCurrentView().CoreWindow.Dispatcher;

// Second way
Window.Current.Dispatcher;

I wonder which one is correct? or if both are equivalent?
