  • WPF VisualBrush Magnifier Updated

    A couple of years ago, I showed an example where I used a VisualBrush to add a magnifier to a WPF application. The example used to be built around Beta 1 of WPF. I finally got around to updating the sample so that it runs with the final release of WPF. Mostly it was a case of updating the XML namespaces, and expanding out the linear gradient brushes. (You used to be able to specify a gradient brush inline in a XAML attribute, whereas you now have to expand the thing out in full.) But I was able to simplify a couple of things too.
