What I have tried:

CspParameters parameters = new CspParameters(1, "Microsoft Base Smart Card Crypto Provider");

AsymmetricAlgorithm asymmetricAlgorithm = new RSACryptoServiceProvider(parameters);

string pubKeyXml = asymmetricAlgorithm.ToXmlString(false);

X509Store x509Store = new X509Store(StoreName.My, StoreLocation.CurrentUser);

x509Store.Open(OpenFlags.OpenExistingOnly);

I would guess it is because you are trying to activate "Microsoft Base Smart Card Crypto Provider".

Do you know how to solve this problem?

What problem? Why are you trying to use the Smart Card Crypto system if you do not have a smart card?

My software communicates with the smart card, but in some situations Windows throws me a dialog with the content Windows security smart card select a smart card device. When Windows throws out a dialog, the execution of my program stops until the user clicks the confirm button on the dialog. Since my software is on the server, the clients are not able to confirm the dialog. Is there any other way to communicate with the smart card to avoid the Windows security smart card alert. Sorry for bad English :)

Is your smart card connected to your server, and configured for use by the AppPool / service account you're using?

If you're expecting code running on the server to use a smart card connected to the user's computer, then you're about to be sorely disappointed.

Desktop application that reads the card is located on the server, and other client computers contact my application on the server through appropriate api calls. I only have one smart card and it is on the server. Only problem is Windows security smart card...
