XPO Automatic Properties

Project Description
Shows how to use PostSharp to allow the use of C# automatic properties with the Express Persistent Objects (XPO) ORM from Developer Express.

Typically in the Express Persistent Objects (XPO) ORM from Developer Express your code would look something like:

public class Customer: XPObject
{
  private DateTime date;
  public DateTime Date
  {
    get { return date; }
    set { SetPropertyValue("Date", ref date, value); }
  }

  [Association("CustomerOrders", typeof(Order))]
  public XPCollection<Order> Orders 
  { 
    get { return GetCollection<Order>("Orders"); } 
  }
}

This project uses PostSharp to let you take advantage of C# automatic properties in XPO, leading to less code to write:

public class Customer: XPObject
{
  public DateTime Date { get; set; }

  [Association("CustomerOrders")]
  public XPCollection<Order> Orders 
  { 
    get; private set; 
  }
}

Requirements
You will need to PostSharp version 1.0 and XPO (I've used version 8.2 trial).
