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 build the blazor app you need either Docker installed or you can follow the instructions to install the appropriate .NET SDK locally. For the rest, you only need:
npm install
To build the project and run it locally run
npm run build
npm start
Then you can access it at http://localhost:8080/react-blazor/.
You can follow me on Twitter @boyanio and ask me any questions you might have. You can also open an issue here on GitHub. Pull Requests are welcome too :-)
