Recently, I have worked on almost three projects involving only serilization. I mean pure serialization. Right now i have a work to do, so I just want to save a link on my blog.
This is an excellent article on Serialization and how one can create an advanced Binary Serializer.
Also shows how to perform encrypted Serialization,Compression,etc.
I can also show you real world use of serialization when i talk about it later. Also i would show how to perform FTP UPload/Download in .NET( my latest project is that) using two different ways - using WebClient and other using FtpWebRequest/Response(.NEt 2.0 only)
For now that is it.
