Summary

Through the Getting Started guide today, when you run npx react-native-windows-init, you get a Paper app. There needs to be an option to create a Fabric app instead. While the option to create a Paper app still exists. And eventually, the default should shift to Fabric.

Today the only option for creating a Fabric app is to figure it out on your own, or clone something like this and modify to your needs.
