Important News about CardSpace

1) The XML Namespaces you will find in all the SDK examples are WRONG !!!
Those namespaces come from the pre-release world. 

For Example : http://schemas.microsoft.com/ws/2005/05/identity/iss...
Should be changed to http://schemas.xmlsoap.org/ws/2005/05/identity/iss...

To summarize: where ever you see the name "microsoft.com" in the XML namespace
Change it to "xmlsoap.org"

2) Many people think CardSpace is just another Identity System. It is NOT !!!
Card space is a federated Identity System! This means that the users details are managed somewhere else (In the identity provider) Not in your process. THIS IS GREAT !
(for some people it is difficult to get used to this).
Federated credentials means that in your system there are at least two "domains":
One, to manage the users (and do other things) and another to use the information in the token the identity provider will provide.
If you do not have two or more such "domains" CardSpace is not for you !
This is also why WCF / ASP.Net are the most natural frameworks to use CardSpace.
