With the .NET Framework 3.0 CardSpace bits getting more stable, its time to take a poke at the technology. After the great success of our teams coordination of the launch of http://www.netfx3.com we recently setup a CardSpace sandbox at http://sandbox.netfx3.com/ .

So what have we done? Well like most sites on the web today, this site provides the ability to login using a username and password (nothing new).   However, this site has been also been customized to also use Windows CardSpace for authentication.  On the Sandbox site you can:

• - Create a user account using a username and password or using a self-issued Windows CardSpace Information Card
• - Link one or more Information Cards with your user account
• - Sign-in to the site using your username and password or an Windows CardSpace Information Card that you have linked with your account

For anyone who installs IE7 Beta 3 and the July CTP of the .NET Framework 3.0 they will be able to show a simple demo to their colleges?

Very cool.
