Entity Framework on model create pass arguments in constructor

Question

When Entity Framework retrieves data from database and creates a new model class for that, how to pass values to the constructor instead of assigning them to the properties?

For example :

public class Customer
{
    public string FirstName { get; set; }
    public string LastName { get; set; }

    public Customer(string firstName, string lastName)
    {
    }
}

So when I call to _context.Customers.ToList(); I want to pass values to the constructor, instead of assigning them to the properties.

Please always tag the applicable EF version. The differences between versions can be significant, esp. core vs. "classic". EF-core now supports entity types with constructors. By the way, I don't see what calling ToList() has to do with constructors. — Gert Arnold

It's not possible, Entity Framework constructs entities using parameterless constructors and sets the properties value using setters. Although, neither parameterless constructor nor setters have to be public.
