I'm trying to get a WPF development environment set up at home, using Visual C# Express 2008. I installed both it and the MSDN documentation for it, however it looks like the documentation doesn't include any WPF documentation.
I was about to install the Windows Vista SDK, however it looks like that only includes the documentation for .NET 3.0, not 3.5 SP1. Where can I download the documentation for .NET 3.5SP1 and (ideally) have it integrated with the documentation that I already have?
