            [Persistent("USER")] 
public class User : ISelfContainingObject 
{ 
    // ... Other properties and fields. 
} 
  
// ... Other code 
  
// Loads a user object from the storage. 
ISelfContainingObject user =  
    (ISelfContainingObject)context.GetObject<User>("Id = {0}", "1"); 
// Checks if the object has been loaded. 
if (user.ObjectInfo.ObjectState == ObjectStates.Loaded) 
{ 
    Debug.WriteLine("Object has been loaded."); 
} 
    

Remarks

This class contains all information to save a persistent object to any kind of device. It makes the persistent object independent from the ObjectContext. This object is returned by the ISelfContaining interface that is implemented if an object is remoted or persisted to a device (other then a storage). The interface should also be implemented if the object is loaded with one ObjectContext and then saved with another.

Attention: Please do not change any properties of this object from your code, since this could affect the stability of your application! If you implement some new kind of IConcurrencyManager you have to populate the ConcurrencyData property with your concurrency data. Other properties are not required to modify.
