SerialSebXamlPadX V3.0
Lester just announced (well, on Wednesday but I have a big backlog because I spend my time reading the alt.net chat) XamlPadX 3.0. I know we didn't use the tool on my previous WPF projects, but I think it's the only XAML quick and easy tool that has seen an update recently. Will need to have a play during the festive season!
