I’ve updated my demo of the Composite Silverlight Library I built to work with Silverlight RTW. The P&P group has plans to ship the next version of the PRISM library (PRISM 2.0) that supports Silverlight, so I’ve started to use their bits instead of the ones that I built with this sample. Bellow is a screenshot of the conversion. As you can see, the default styles in Silverlight 2.0 have been changed, and the rendering is much better.
