I got a lot of great feedback on my post Silverlight 3 Navigation: Dynamically Loaded Pages… Now MEF Powered!

Dinesh Chandnani decided to do an update to this sample after looking at the feedback and talking to Nikhil Kothari and Wes Haggard from the MEF dev team.  The goals for this update are:

  1. Show even more of a web like user model.  With the web, you often see all the links in the navigation, but the actual page only downloads once the user clicked the link. 
  2. Lose coupling.  I need to be able to be able dynamically add, update even remove pages from my application without taking down the app and without rebuilding it.
  3. Built in authentication.  In real business apps, we need to protect our data, so authentication is  very important.  The web has popularized a very interesting model where you are only asked to authentication when you try to do an operation that needs it.  For example, i can browse the netflx catalog any time, but I have to log in the minute I try to add something to my queue.
