Can React Native Windows be used like a brownfield library (dll) as on iOS/Android?

[iiliev-nemetschek]

Question:

On iOS and Android, React Native can be integrated into an existing ("brownfield") app as a library (framework/dll), allowing the host app to show a screen or view with a React Native component as needed. The host app remains a native project, and React Native is used just for specific screens or features.

Is it possible to achieve a similar integration pattern with React Native Windows?

Specifically:

• Can I build React Native Windows as a DLL or library that can be imported into an existing Win32/WinAppSDK or WPF/UWP app?
• Can the host app create and show a window with React Native component, similar to how it works on mobile?
• Are there example projects, documentation, or architectural guidance for this kind of use?

Any insights, limitations, or architectural considerations for brownfield (library) integration on Windows are appreciated!
