What is the easiest way to save an Observable collectin of object to an XML file?

Question

I\'ve have an Observable collection containing customer objects:

  public class Customer
  {
    public string FirstName { get; set; }
    public string Last

XML serialization :

ObservableCollection<Customer> customers = new ObservableCollection<Customer>();
...

XmlSerializer xs = new XmlSerializer(typeof(ObservableCollection<Customer>));
using (StreamWriter wr = new StreamWriter("customers.xml"))
{
    xs.Serialize(wr, customers);
}

To reload the data from the file :

XmlSerializer xs = new XmlSerializer(typeof(ObservableCollection<Customer>));
using (StreamReader rd = new StreamReader("customers.xml"))
{
    customers = xs.Deserialize(rd) as ObservableCollection<Customer>;
}
