Sample project to demonstrate how we use ODataAPIHandler in OData bulk operations
A bulk operation is an operation that allows you to carry out several operations (insert, update, delete) on several/single resources (of the same type) and their nested resources (to whichever level) using a single request.
In this sample project we have Customer entity with related Order. The relationship is many to many.
public class Customer
{
[Key]
public int Id { get; set; }
public String Name { get; set; }
public int Age { get; set; }
public List<Order> Orders { get; set; }
}
public class Order
{
[Key]
public int Id { get; set; }
public int Price { get; set; }
public int Quantity { get; set; }
public List<Customer> Customers { get; set; }
public ODataIdContainer Container { get; set; }
