Implementing STS for Infocards

I have been trying to use Infocards in my WinFX app and had some problems in using them. I was not able to import my self-created Infocards into my identity store. The problem was that when importing the infocard into the identity store, it was checking for the provider address where an STS(Security Token Service) needs to be running which was not the case in my system. Searching for a solution came across this STS implementation in Martin Gudgin's blog.
