title: Useful WPF utilities
body: <p>What are some useful utilities that help you when writing WPF applications? I know about <a href="http://blois.us/Snoop/" rel="noreferrer">Snoop</a> for visual debugging of WPF applications at runtime, and <a href="http://blog.wpfwonderland.com/2008/10/08/shazzam-wpf-pixel-shader-effect-testing-tool-now-available/" rel="noreferrer">Shazzam</a> - a WPF pixel shader effect testing tool.</p>
