We could configure the relationship using the Fluent API with the HasOne, WithOne, and HasForeignKey methods. The HasForeignKey method needs to be generic in a one-to-one relationship (a one-to-many relationship doesn't require this) since we need to explicitly mark the dependent type. In our case, we have specified the Address entity for the foreign key:
protected override void OnModelCreating(ModelBuilder modelBuilder) { modelBuilder.Entity<Blog>().ToTable("Blog"); modelBuilder.Entity<Post>().ToTable("Post"); modelBuilder.Entity<User>() .ToTable("User") .HasOne(x=>x.Address) .WithOne(x=>x.User) .HasForeignKey<Address>(x=>x.UserId); modelBuilder.Entity<Address>().ToTable("Address"
