There is only one problem with this: your code can only handle (public) properties. Actually an object serialised by your code and then deserialised could stop working properly because Private variables not bound to properties (which weren't saved therefore) may not contain the right values anymore. > What do you think?

I think the solution to both above problems is already in Settings.Write(). It is capable of _correctly_ writing and restoring objects if they export a Settings property. As a matter of fact, the object itself only really knows what must be serialised and can also provide its private variables. Alas, I don't see how the serialisation process could be done _without_ the object being deeply involved by providing its internal information.
