For Asp.net core with react , what is the best project architecture

Thank you. this means there will be 2 projects 1 project for react (UI) and 1 project for ASP.NET WebAPI (for api).  

 

 

also, as per my understanding, razor pages , views in mvc are not used in the real time projects as UI is done in react.... is my understanding correct? please advise. 

Yes, 

React (UI) -----> WEB API [EF-->DB]
