All of the work in .NET Core benefits ".NET Native". .NET Native is what powers the .NET stack side for Universal Windows Platform (UWP) apps.
WinForms has been considered deprecated since WPF and WPF is essentially deprecated for UWP. (In an interesting historical aside, in some ways the UWP is what WPF was promised to be way back when WPF was still codenamed Avalon.)
Certainly WinForms and WPF aren't going anywhere any time soon (both in terms of backward compatibility will be stable for a long time still, but don't expect any new things), but UWP is clearly the way forward for new apps and it is benefiting from the work going into .NET Core.
The Desktop App Converter recently released (nee Project Centennial) can help if you've got a big investment in WinForms and wish to slowly migrate to UWP, so you aren't necessarily "stuck" in the past if you do want to try to move forward.
