I like the idea of CardSpace but unlike OpenID it seems like a real PITA to support it in your ASP.NET web application. I've found many examples, even a tutorial in one of the books I own... but it would seem a lot more is required than what they suggest.
Changes to the server and such?
Can someone tell me:
I think the complexity (or poor documentation) is one of the reasons CardSpace is lagging behind.
(I'm interested in what others think about this, but lets not turn this into a flame war, I just want a solution and perhaps your thoughs in short)
I have blogged about that, but it is in Swedish. I hope we can rely on google translate. :-)
Use Windows CardSpace with ASP.NET Membership
Get an InfoCard with Javascript
Hope this helps.
