There have been a lot of questions recently about how to write authorization-enabled UI in Silverlight. We’ve always floated suggestions from the RIA Services team, but never put something concrete together. I decided to take some of those ideas and run with them. So today I’m excited to announce we’ve made an authorization sample available. The core functionality is located in a single Silverlight assembly so it’s easy to reuse. Please take a look and let me know what you think. I’m still actively developing this so I appreciate any and all feedback.

Authorization based dynamic UI and Navigation

This sample shows how to use client-side authorization to customize UI and authorize navigation through xaml markup. The main functionality is contained in a Silverlight library to make it portable and reusable. Included with this sample are guides that cover common scenarios to make client-side authorization easy to understand and implement.

[Security Note]
Authorization in Silverlight should only be used for Navigation and UI customization. For true security, you need to secure your data by adding authorization to your web services. These msdn links describe how this can be done using WCF RIA Services.
