Hello

The following line of code throws an exception" The System Cannot find
the file specified".
This is on .Net 2.0.

RSA rsaKey = new RSACryptoServiceProvider(); //Creating with Default
key

Appreciate the help
Thanks

rsaKey shows up as follows during debugging.

-rsaKey
{System.Security.Cryptography.RSACryptoServiceProvider}
     -base
{System.Security.Cryptography.RSACryptoServiceProvider}

     KeyExchangeAlgorithm    "RSA-PKCS1-KeyEx"

     - KeySize     ((System.Security.Cryptography.AsymmetricAlgorithm)
(rsaKey)).KeySize'
                              threw an exception of type

'System.Security.Cryptography.CryptographicException'

     +base            {"The system cannot find the file specified.\r\n"}

Is this a web app or Win Forms?
The associated account for the app should have rights over the key
store so that the key can be created.

There are already a couple of similar threads out there.
