>Wow, that sounds like a lot of unnecessary work! You can sub-class Typed DataSets to add functionality to them and still pass around those DataSets instead of BizObjects. I dunno ... maybe it's six of one, half dozen of the other. <g>

Those are the two schools of thought that I've seen for business objects on the .NET world. Some people build their business objects around datasets (kind of decorated datasets) while some other people build business objects that implement the ISomething interface (I forget the name)

From what I've seen it's a lot of work either way, maybe I should buy MM.NET :)
