Serialisation

This is the mechanism that allows us to represent objects in persistent text form.

Deserialization

This allows us to convert a data stream back into an object

DataContract

NetDataContract

This is similar to DataContrctSerializer and has the same interface
This class however does not require the types to be explicitly registered for serialisation.

Formatters

XML and Binary

Binary Serialisation

There are two ways to support this
The first is using the {Serilizable] attribute

XML Serialisation

Attribute based

Derived Classes

A child object is an instance of a derived class
