Subtly and quietly, Microsoft has been removing WPF resources from the MSDN site. If you click on the link that used to take you to the WPF home, you will be directed to the general Visual Studio .Net Framework home.
WinForms has been a thorn in Microsoft’s side for a while and it would appear that they want to remove the WPF thorn as quickly as possible. It’s a shame, really, WPF has some really good qualities.
I can’t really complain though. If you look at something like Java/Swing/AWT/JavaFX, Oracle can’t pull it all together fast enough. Sure the toolsets have really improved, but the base product itself (the libraries) just aren’t up to snuff.
That’s my two cents worth.
