Yes, I've tried this in one of my recently EF Core project.
For the parent class and child classes, it will AS IS what we doing usually.
For example:
```C#
public abstract class Function { ...}
public class Menu : Function {...}

In the DBContext class, we can expose above classes to DBSet, and only need to define the Entity for `<Function>` :
```C#
public class MyDBContext : DbContent
{
        public virtual DbSet<Function> Functions { get; set; }
        public virtual DbSet<Menu> Menus { get; set; }
...
        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
...
modelBuilder.Entity<Function>(entity =>
            {.....});
....
}

But if you want to have any other specific requirements such as Ignore Properties of sub class, you can continue declare these, for example:
C# modelBuilder.Entity<Memu>().Ignore(e => e.MenuProperty1);
