.NET developers only started taking WPF seriously after the performance improvements Microsoft did to WPF, which took place after Visual Studio team adopted WPF to prove its quality.
If you intended to do any remark regarding UWP, first WPF is not going anywhere as communicated to those that care to learn what goes at Build, and second the architecture between WPF, Silverlight and UWP is almost the same, just a few differences regarding XAML features and .NET APIs.
The next version of Office and Note for Windows 10 are going to be store only.
At Build they also had people from Adobe, Cakewalk and Kodi showing their desktop apps ported to the UWP via the Desktop Bridge.
Like they did with WPF and Visual Studio, they are pushing everyone into the train by dragging their own devs into it.
