Serialization does not support appending (at least not that I have read
anywhere, MSDN does not explicitly say this, but given how serialization
works, I can't imagine that it does work).
If you need to modify a serialized component, then you should deserialize it
first, then make your changes and then serialize it back, overwriting the
original file.
