Ahh, I see... Well, no, it's not type-safe, but it feels a bit more OO at least :)
Regarding .NET 2.0, yeah, I'd love to make the switch, but unfortunately it's not up to me alone... :( All my new projects are in .NET 3.5 and this project is also converted to VS 2008 so I'm using the .NET 3.5 compiler targeting 2.0 (gives me auto properties and the nice var :) ) Furthermore we are still hosting some projects on a Windows 2000 Server, and Microsoft has decided not to support .NET 3.5 on this platform... Grrr!
