Nice Silverlight 2 Business App Design with Source Code
My sense is that Silverlight 2 is going to have a major impact in business applications because of its security, programmability, and ease of deployment. I'm currently working on a prototype for a client who would use the application mainly within the office but who sees a big bonus in allowing employees to log in after hours from any computer to handle emergency/on call tasks.
The best business design example I've seen so far is the Microsoft Health Common User Interface Patient Journey Demonstrator. The source code has been updated to the RTW version of Silverlight 2. This app shows a huge number of techniques including forms, attractive lists, drag 'n' drop, control resizing and search functions.
Unfortunately, the application's sample data comes from static XML files. If the Microsoft Health CUI Team could implement its patient registration form using web services against a real SQL Server database, this would be a spectacular offering.
