RSACryptoServiceProvider - fail to get KeyContainerName from the certificate PrivateKey in mta mode

Question

I have constructed a WPF application that digitally signs documents by using a smartcard.
The application reports progress to the user through the displayed window.
The all signing process takes place in a different thread in order to be able to update the displayed window.

The problem is, whenever I access the KeyContainerName through the certificate PrivateKey, the application hangs and that's how it remains, until the undesired process termination.

This is a code snippet of the troublemaker code:

  CspParameters csp = new CspParameters();
                csp.KeyContainerName = ((System.Security.Cryptography.RSACryptoServiceProvider)certificate.PrivateKey).CspKeyContainerInfo.KeyContainerName.ToString();

* The certificate is being extracted from the user store after inserting the smart card.

Answer 1

Hi,

Where do you call the statements above? from main thread?
Could this caused the application need to retrieve info from the card?
