Ajax Control Extender for CardSpace
Another bright colleague at Readify, Daniel Bartholomew has just published an Ajax control extender to enable CardSpace authentication. Daniel has been working with CardSpace for quite a while now and this should be a worthwhile addition to the Ajax Control Toolkit.
It enables you to easily add CardSpace authentication to your web site. Daniel has just posted it up to CodePlex. You can find it here: http://www.codeplex.com/CardSpaceAjax
