Now code will look like this:

Version 2

[Serializable]
class NewItem
{
[OptionalField]
private string _name;

public string Name
{
get { return _name; }
set { _name = value; }
}
}

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

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

[OptionalField]
private List<NewItem> _newItems;

public List<NewItem> NewItems
{
get { return _newItems; }
set { _newItems = value; }
}
}

And code for serialize and deserialize

private static byte[] SerializeData(object obj)
{
var binaryFormatter = new BinaryFormatter();
using (var memoryStream = new MemoryStream())
{
binaryFormatter.Serialize(memoryStream, obj);
return memoryStream.ToArray();
}
}

private static object DeserializeData(byte[] bytes)
{
var binaryFormatter = new BinaryFormatter();
using (var memoryStream = new MemoryStream(bytes))
return binaryFormatter.Deserialize(memoryStream);
}
