How to implement a one to one relationship in Entity Framework?

Question

C++ / C#

Hello! I have 3 entities User, Mentor and Student. Mentor and User have a one-to-one relationship, Student and User also have a one-to-one relationship. Also, they must have the same Id. That is, when we want to add a Mentor object, there must already be a User object with the same Id. Also with Student.
But how can this be done? I'm just new to Entity Framework

Read - everything is well written here .
From the point of view of the database architecture, if there is a one-to-one relationship, then it might make sense to combine the data into one table.
