I have created a WPF/E CardSpace sample based on Vittorio's outline.

I runs well at https://www.dbartholomew.net/wpfe_example/default.html.

To make my site look a little better I created the WPF/E tab that you can see on the left, and added an IFrame module to the page.

However, the sample doesn't work in the IFrame - even though the page is loaded using SSL.

This has lead me to the conclusion that the entire page must use SSL, not just the page containing CardSpace based code.

I have a temporary problem forcing the WPF/E page to use SSL, this should be fixed within a day or so.
