Some gotchas in backward compatibility

This small example shows how you can lose backward compatibility in your programs if you do not
take care in advance about this. And ways to get more control of serialization process

At first, we will write an example of the first version of the program:

Version 1

[Serializable]
class Data
{
[OptionalField]
private int _version;

public int Version
{
get { return _version; }
set { _version = value; }
}
}

And now, let us assume that in the second version of the program added a new class. And we
need to store it in an array.
