WCF client with SmartCard certification works on Win7, but not on XP?

Well, after a month or so trying to solve this issue, the conclusion is that THIS ISSUE CANNOT BE SOLVED . At least it cannot be solved with native . NET and OS support.

Windows XP is apparently too old for the Microsoft to support AES 256 bit encryption, SHA 256 bit signing with RSA for key exchange. There are 40% of users in the world still using XP, so this decision is really strange.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
