Fix access to DateTime fields in Windows.Storage

[morali]

You cannot use directly datetime fields anymore, so Windows.Storage needed changed to apply correct date to files.

Description

After updating nF extension to latest version, setting datetime fields didn't work anymore. Accessing date created filed in VS caused instant hardfault. I changed the code to fix this problem.

Motivation and Context

How Has This Been Tested?

Tested with sample files from nF.
