I've looked at the code for the infamous Josh Smith artice in MSDN magazine and am having trouble seeing how a Dataset could be worked into the ViewModel.
Is there a good example out there that ties a Dataset with the MVVM pattern?
I took a quick look at NHibernate, but I'd rather stick with libraries that are part of the Framework, at least until I get a handle on MVVM.
Like I said, this is data, and data is handled the same whether it's done from MVVM or the code behind. To make it more concrete, your ViewModel would expose the DataSet, and the View would data bind to it.
