Answer 1

Figured it out. Replaced sslStream.AuthenticateAsClient("gateway.sandbox.push.apple.com"); with sslStream.AuthenticateAsClient("gateway.sandbox.push.apple.com", clientCertificateCollection, SslProtocols.Default, false); And registered the certificates on the PC.

Edit: Here is the code for creating a payload as requested:

    private static byte[] GeneratePayload(byte [] deviceToken, string message, string sound)
    {
        MemoryStream memoryStream = new MemoryStream();

        // Command
        memoryStream.WriteByte(0);

        byte[] tokenLength = BitConverter.GetBytes((Int16)32);
        Array.Reverse(tokenLength);
        // device token length
        memoryStream.Write(tokenLength, 0, 2);

        // Token
        memoryStream.Write(deviceToken, 0, 32);

        // String length
        string apnMessage = string.Format ( "{{\"aps\":{{\"alert\":{{\"body\":\"{0}\",\"action-loc-key\":null}},\"sound\":\"{1}\"}}}}",
            message,
            sound);

        byte [] apnMessageLength = BitConverter.GetBytes((Int16)apnMessage.Length);
        Array.Reverse ( apnMessageLength );
        // message length
        memoryStream.Write(apnMessageLength, 0, 2);

        // Write the message
        memoryStream.Write(System.Text.ASCIIEncoding.ASCII.GetBytes(apnMessage), 0, apnMessage.Length);

        return memoryStream.ToArray();
    } // End of GeneratePayload
