Proposal: Provide Mechanism for Sharing Styling Resource from UWP Islands -> WPF

Summary

Styling resources are not capable of mapping back out from a UWP Island into Win32; which makes coloring/styling/theme awareness something that needs duplication across components and requires strict coordination to make changes to.

Rationale

E.g., see this PowerToys issue where, because the WPF TitleBar is not theme aware, an instance of PowerToys running in Dark Mode still has a Light Mode TitleBar.

Important Notes

• Resources are of different data types between UWP and WPF,

Open Questions

• Noting that these resources are of different data types between UWP and WPF, PowerToys proposed the idea of having a wrapper class that could bound to on the WPF side?
• Design Tokens a possible solution?

@SavoySchuler Interesting problem. Do we have any potential solutions that have been put forward? Can you summarize what the customers like PowerToys would like to see here?
