is "using" slower than direct referencing to the name space in winrt?

Question

we have two ways of coding. Which one is the better approach?

var visibility = Windows.UI.Xaml.Visibility.Collapsed;

or

using Windows.UI.Xaml;
var visibility = Visibility.Collapsed;

No. It makes no difference¹

The compiled code is the same. The using Directive merely instructs the compiler how to resolve the types used.

¹ This is true of C#; WinRT or WPF or XAML does not change this.
