Joshua Flanagan has recently published his latest update to a new ProfileView control he has built that enables you to view/edit ASP.NET 2.0 Profile settings within a web-page. It is a pretty cool control definitely worth checking out if you are using the new profile system.
He also has some great posts a little earlier on his blog on how to access configuration at design-time in VS 2005, and a VS 2005 Project Template for building ASP.NET 2.0 Role Providers.
Update: Alex has posted a very cool sample that shows using this control here. Definitely check it out!
Hope this helps,
Scott
