When I use the web application, the application logs me out. I think it might be an IIS recycle.
EventViewer Message:

I solved this problem. Solution Steps:
!analyze -vWindbg analized and show a text like this:

So I added this code to Decrypt Method: if (String.IsNullOrEmpty(value)) return String.Empty;
public static string Decrypt(string value)
{
SymmetricAlgorithm algorithm = SymmetricAlgorithm.Create();
ICryptoTransform decryptor = algorithm.CreateDecryptor(EncryptionKey, EncryptionVector);
// I control value
**if (String.IsNullOrEmpty(value))
return String.Empty;**
byte[] encryptedBytes = Convert.FromBase64String(value);
MemoryStream memoryStream = new MemoryStream(encryptedBytes);
CryptoStream cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read);
...
}
problem was solved.
