Every entity that holds a reference to another entity should have a property named ForeignEntityId (note the lower case d in Id).

If you set up your entities following the exact pattern of this example, all your columns should be named according to convention:

public class Customer
{
    public int Id { get; set; }
    public string Name { get; set; }

    public virtual ICollection<Order> Orders { get; set; }
}

public class Order
{
    public int Id { get; set; }
    public int CustomerId { get; set; } // this property is important
    public string ProductName { get; set; }
    public decimal Price { get; set; }

    public virtual Customer Customer { get; set; }
}
