EF Core Complex Property

As of EF Core 8, it's now possible to specify a class or a structure as a Complex Type. The following example specifies that the Address structure should be considered as a complex type:

public class Order
{
    public int OrderId { get; set; }
    public DateTime OrderDate { get; set; }
    public Address ShippingAddress { get; set; }
    public Address BillingAddress { get; set; }
    //... other order-related properties
}

public struct Address
{
    public string Street { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string Country { get; set; }
    public string PostalCode { get; set; }
    //... other address-related properties
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
	modelBuilder.Entity<Order>(x => {
		   x.ComplexProperty(y => y.ShippingAddress, y => { y.IsRequired(); });
		   x.ComplexProperty(y => y.BillingAddress, y => { y.IsRequired(); });
	 });

	base.OnModelCreating(modelBuilder);
}

NOTE: When specifying a ComplexProperty, you must also specify the navigation IsRequired in your fluent mapping.
