[IProjection] public class CustomerProjection { public Guid Id { get; set; } public string Name { get; set; } public string Address { get; set; } }
public interface ICustomerRepository { [Projection(typeof(CustomerProjection))] CustomerProjection Get(Guid id); }In this example, the ICustomerRepository interface includes a method called Get, which returns a CustomerProjection. The [Projection] attribute is used to indicate that the method returns a projection of the domain entity. The IProjection attribute is typically included in a package or library that implements DDD concepts, such as the Microsoft.CSharp.DesignPatterns library.
