object persistence?

I read somewhere that the 2.0 framework would have built in support for object persistence. Does anyone know where i can find documentation/samples for this feature?

Thanks,
LyndonWith ObjectSpaces you can define classes and relationship between classes with XML and retrieve and store object(s) to a data source.

You also have User Defined Data Types (UDTs), with defines classes that could be saved into a database (Yukon is required). You can read about UDTs on this site:

Thank you. I stumbled upon that article about objectSpaces a couple of days ago, but didn't bookmark it. That is precisely the link i was hoping someone would post.
