Kim Cameron has just blogged Christian Arnold’s release of a Visual Studio Tookit for Cardspace that integrates Cardsapce with the ASP.Net Membership subsystem. If you are interested in learning about the Carspace Toolkit for Visual Studio visit Kim's blog. You can download the tools here.
I will be presenting Cardspace and WPF at the upcoming Code Camp on March 31st. I hope to see you there. -bob
