I am trying to create a conceptual diagram after researching for a while, it seems like you need to use minimal API if you want to mesh it with a React frontend. Is it possible to do this with the MVC architectural pattern?
I have read the docs and watched numerous tutorials but could not find the answer.
Is there a reason you want an "MVC architectural pattern"? I think the way to do this is with a ASP API backend. If you are not familiar with an ASP API it has the feel of a MVC app and might be what you're looking for?
Take a look at this link:
This link shows you how to easily get a template solution setup with a React SPA and a ASP.NET Core API project as the backend.
