I am not sure why people are not really talking a great deal about Windows CardSpace (formerly "InfoCard") as they do about other netfx3 technologies like WCF, WPF and WWF. This seems to be a really interesting technology to me and will redefine the way we are going to provide user identity to various applications. I thought there would be at least one session on CardSpace in TechEd 2006. But to my disappointment, there were none. Windows CardSpace enables users to provide their digital identities in a familiar, secure and easy way. In the physical world we use business cards, credit cards and membership cards. Online with CardSpace we use a variety of virtual cards to identify ourselves, each retrieving data from an identity provider. Don't struggle with usernames and passwords, just choose an information card!
