Workaround:

If you were looking for information on custom certificate validation, you can often achieve this using the `RemoteCertificateValidationCallback` property of the `System.Net.Security.SslStream` class or by implementing a custom `ICertificatePolicy`.

Example (Conceptual):


// Note: This is a conceptual example and may not be directly applicable
// if ValidationCASPer itself is undocumented or removed.

using System;
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;

public class CertificateValidator
{
    public static bool ValidateServerCertificate(
        object sender,
        X509Certificate certificate,
        X509Chain chain,
        SslPolicyErrors sslPolicyErrors)
    {
        // Default validation behavior for demonstration
        if (sslPolicyErrors == SslPolicyErrors.None)
            return true;

        Console.WriteLine($"Certificate error: {sslPolicyErrors}");

        // Add custom validation logic here, e.g.:
        // - Check if the certificate is issued by a trusted authority.
        // - Check if the certificate's subject name matches the server's hostname.
        // - Check certificate revocation status.

        // For demonstration, return false if there are any errors not handled.
        return false;
    }

    // Example usage within an SslStream setup:
    public void ConnectWithCustomValidation()
    {
        // Assuming 'tcpClient' is an established TcpClient connected to a server
        // and 'sslStream' is obtained from it.
        // SslStream sslStream = new SslStream(tcpClient.GetStream(), false,
        //     new RemoteCertificateValidationCallback(ValidateServerCertificate));

        // sslStream.AuthenticateAsClient("your.server.name");
        // ... use sslStream ...
    }
}
