Nope, There is no smaller download for Orcas. If you really want to d/l smaller, your option is to use the WPF extensions for Visual Studio 2005. It still requires that you download the Vista SDK which is almost 1.1 GB (don't try to install it from the web - d/l the full ISO). Your other option will be to use either Cider (google for Microsoft Cider) if you can find it, or to use Aurora XAML designer (google for it as well). Personally I am using Orcas, due to the presence of Linq. Cheers
