Hi Developers, I am creating asp.net core 2.1 project with postgresql.
I need to create new 4 tables everytime when user register on my Website
(it means when new row inserted in User table,new 4 tables created automatically).
I search a lot,but not find any way to solve this using entity framework core.
I also want to use SQL Stored procedures and Views in this Project.

1) How can i solve this using entity framework core?
2) May i need to use ado.net for this rather than efcore?

What I have tried:

I tried using Npgsql.EntityFrameworkCore.PostgreSQl but can't create, what i needed.
