I'm having some problems with a pfx file in a Silverlight App, I need to sign a xml file with a pfx certificate. But I was unable to import the pfx file in a System.Security.Cryptography.X509Certificates.X509Certificate object, so i want know if the ncryptoki can import the pfx certificate in a Cryptware.NCryptoki.X509Certificate object using Silverlight.

I'm already using ncryptoki because i'm using another certificate from a token.
