How to digitally sign PDF files with smartcards in .NET?

Question

I have a smartcard that stores my digital certificate. When I plug it into my PC, the certificate shows up at the Windows certificate store, under IE > Tools > Internet Options > Content > Certificates.

So... How can I use such certificate to sign a PDF file in .NET?

Check http://itextpdf.sourceforge.net/howtosign.html. Maybe you need to change the key store to the "Windows-MY" keystore.
