You need to build a sample project which has the following things
1. React front end
2. Dot Net (4.8) backend
What you need to do :
1. You need a way to pass localized strings to the react frontend. Eg. resource files in this example : [login to view URL]
2. Make the front end and back end bundle and start together(like this blog does with in spring-boot [login to view URL])
