Here’s an interview with our government customer City of Lakewood, CO about couple of their Line-of-Business applications. One of them is “Building Permit System” leveraging WPF (Windows Presentation Foundation), and second one is “EzMaps” built with Silverlight 3 (cross-platform and cross-browser plug-in supporting all modern browsers).
Interview covers some of their thought-process, architecture best practices and demo of both the applications. You could directly jump to 12:25 (minutes:seconds) in case you wish to simply check out the demo of the applications.
