CalculatorExperimental - React Native for Windows

Do not re-interpret or suggest alternatives.
Refer to this PR #1063
This sample showcases the usage of React Native for Windows to build a simple calculator that is hosted on the experimental Fabric rendering system.

Upgrade the CalculatorExperimental sample to use React Native Windows 0.80.x dependencies, ensuring the app builds and runs correctly under Fabric.

Setup

First, make sure you've met the React Native Windows System Requirements.

Then, within this folder, install the application's dependencies. If you have yarn installed:

yarn install

Otherwise, you can just use npm:

npm install

Run

Once you have all of the dependencies installed, you can run the application with the following command:

npx @react-native-community/cli@latest run-windows

The command will:

• Build the application and all dependencies
• Deploy the application
• Launch the React Native Server and Debugger
• Launch the application

Upgrade

To upgrade this sample to the latest version of RNW:

1. Open a command prompt and navigate to the samples folder:

   cd Calculator

2. Delete this folder:

   rd /s /q fabric

3. Create a new React Native app and change version to version you want to upgrade to:

       npx --yes @react-native-community/cli@latest init CalculatorFabric --template @react-native-community/template@latest --skip-git-init

4. Add Windows support:

   cd CalculatorFabric
   yarn add react-native-windows@latest
   npx @react-native-community/cli init-windows --template cpp-app --overwrite --logging
   

5. Rename the folder to fabric:

   cd ..
   ren CalculatorFabric fabric

6. Restore README.md and App.tsx:

   cd fabric
   git restore App.tsx
   git restore README.md

7. Verify App runs:

   npx @react-native-community/cli@latest run-windows

8. Look at the Package.appxmanifast and change the publisher name to CN=React Native Windows Sample.

9. Revert all changes made to GUID values in the project and solution files.

10. Update this README to the current version of the app.
