WPF, Silverlight and XAML
I don’t get a chance to try out many WPF Custom Controls, but I like to pass on pointers as I see new ones. Mindscape just released a Flow Diagram control for WPF.
JD announced it on his blog: http://blog.bluecog.co.nz/archives/2009/02/25/we-shipped-wpf-flow-diagrams/
He links to several screenshots, trial download, etc…
I tested Mindscape, it has bugs in their demos.
