You can view the changes made to the default new React Native Windows applications for C++ and C# using React Native Upgrade Helper. See this document for more details.

Starting with React Native Windows version 0.80.0, the New Architecture will be enabled by default. It is strongly recommended to move to the new architecture as soon as possible to take advantage of improved performance, long-term support, and modern capabilities as paper architecture will not be supported from React Native for Windows v0.82.

Progress Towards Feature Parity on Fabric

| Core Component | Fabric/Paper | Parity % | |----------------|--------------|-----------| | View | 40/40 | 100% ✅ | | ActivityIndicator | 3/3 | 100% ✅ | | Image | 14/14 | 100% ✅ | | RefreshControl | 0/2 | 0% ❌ | | ScrollView | 24/27 | 89% | | Switch | 6/6 | 100% ✅ | | Text | 27/29 | 93% | | TextInput | 24/37 | 92% | | Overall | 148/158 | 92% |

Extended Parity Assessment

| Core Component | Fabric/Paper | Parity % | |----------------|--------------|-----------| | View | 129/131 | 99% | | ActivityIndicator | 127/131 | 98% | | Image | 156/157 | 99% | | RefreshControl | N/A | 0% | | ScrollView | 153/159 | 96% | | Switch | 136/138 | 99% | | Text | 154/158 | 97% | | TextInput | 174/180 | 97% | | Overall | 1029/1051 | 98% |

[^1]: An accurate estimation on how many inherited View props and Style props are available in RefreshControl cannot be done until the RefreshControlViewComponent is implemented.
[^2]: Including RefreshControl, the parity progress is estimated to be at 91%.

Notes

View ✅

Full parity achieved!

ActivityIndicator ✅

Full parity achieved!

Image ✅

Full parity achieved — few known issues with SVG and caching.

RefreshControl

Not implemented yet.

ScrollView

Pending support for snapping-related props.

Switch

Almost at parity; only overflow prop missing.

Text

Custom fonts unsupported; clipping issue in nested views inside text.

TextInput

Pending callbacks and selection-related actions; autocapitalize lacks words/sentences mode.

Introduction of Modal in Fabric

Modal replaces Flyout and Popup from Paper.

Supported props: onDismiss, onShow, visible
Planned: Implement title bar and moving capability
Known issue: App crashes when moving window while Modal is open

Suggested Mitigation: Do not move the main window when Modal is open; wait for minor release of RNW v0.80.x.

React Native Gallery Store App Updates
