Predicates in Lambda Expression for Entity Framework Code First

Posted on July 24th, 2013 Sean 1 comment

If I have 2 entities of “People” and “Car”, and “1” People can have “Many” Car, my code first class could be like below:

public class People
{
	[key]
	public int ID { get; set; }
	public string Name { get; set; }
	
	public virtual ICollection<Car> Cars { get; set; }
}

public class Car
{
	[key]
	public string VIN { get; set; }
	public string Maker { get; set; }
	public int OwnerID { get; set; }
	
	[ForeignKey("OwnerID")]
	public virtual People Owner { get; set; }
}
