Dominick and David beat me to the punch; last night I hit the "publish" button on codeplex for SharpSTS; a C# library to allow you to develop Information Card Security Token Services.

As with all open source projects there is still a bunch of work to do; as it stands we have a command line STS which should allow you to get started. Well; if you can work out from the source code what you need to do :)

Over the coming weeks and months I, as dictator, Dominick Baier and David Christiansen hope to deliver a stable, tested, code base from which you can deliver managed information cards to your users, as well as a test web site which will issue and accept managed cards.

In the mean time you can download the code, implement your own authorisation policy provide and get started. In the meantime we’re guiding the rough beast, its hour come round at least, slouching towards Redmond to be born (with apologies to Yeats).
