ObjectContext context = new ObjectContext(new MsSqlStorage("sa", "",  
    "localhost", "application")); 
  
// ... Other code. 
  
// Get the first user matching the name. 
User user = context.GetObject<User>("Name like {0}", "%mith%"); 
  
// Mark the object for deletion. 
context.MarkForDeletion(user); 
  
// Deletes the user object from the storage. 
context.PersistChanges(user); 
    

Remarks

This routine marks a persistent object for deletion. The object is not deleted immediately. It is deleted on the next call of PersistChanges. If you want to delete immediately an object from the storage you have to mark it for deletion and then call PersistChanges.
