This demo shows how React apps can live together with Blazor apps, which are basically C# apps running in the browser with the help of WebAssembly.
To configure Blazor on your machine, you can follow the instructions online. For the rest, you only need:
npm install
To build the project and run it locally, run
npm run build
npm start
The later will create a web site at http://localhost:8080/react-blazor/.
You can follow me on Twitter with @boyanio and ask me questions you might have. You can also open an issue here on GitHub. Pull requests are welcome, too :-)
