Answer 1

Please use following code from github available for .Net push notification. You need to provide .p12 file in it and you have to set developer/production mode according to your requirement.

Answer 2

Below code is for PHP.

There is no such Code readily available. You can do it like maintain 1 tag field in database table like 1 for iOS device and 2 for android device. I have implemented same functionality and below is code for sending push notification accordingly.

//This function determines which is the device and send notification accordingly.
function sendPushNotificaitonToAllUser($NotificationMsg)
{
    $sql = "select ID,DeviceToken,DeviceType from TblDeviceToken";
    $rs  = mysql_query($sql);
    $num = mysql_num_rows($rs);

    if($num >= 1)
    {
        while($row = mysql_fetch_array($rs))
        {
            $deviceToken = $row['DeviceToken'];
            if($deviceToken!='' || $deviceToken!='NULL')
            {
                if($row['DeviceType']==1)   
                    deliverApplePushNotification($deviceToken,$NotificationMsg);
                else if($row['DeviceType']==2)  
                    sendAndroidPushNotification($deviceToken,$NotificationMsg);
            }
        }
    }     
}

//APPLE PUSH NOTIFICATION DELIVERY
function deliverApplePushNotification($deviceToken,$message)
{
    //Create context
    $ctx = stream_context_create();
    stream_context_set_option($ctx, 'ssl', 'local_cert', PEM_FILE_NAME);
    stream_context_set_option($ctx, 'ssl', 'passphrase', APPLE_PEM_PASSPHRASE);

    //Establish connection
    $fp = stream_socket_client(APPLE_URL, $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

    /*
        if (!$fp)
            exit("Failed to connect: $err $errstr" . PHP_EOL);
    */  

    $body['aps'] = array('alert' => $message,   'sound' => 'default'); // Create the payload body
    $payload = json_encode($body); // Encode the payload as JSON
    $msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;// Build the binary notification
    $result = fwrite($fp, $msg, strlen($msg));// Send it to the server


    //If want to keep track of delivery can be done from here.
    /*if (!$result)
        echo '<br/>Message not delivered-->$deviceToken' . PHP_EOL;
    else
        echo '<br/>Message successfully delivered-->$deviceToken' . PHP_EOL;        
    */

    fclose($fp); // Close the connection to the server
}

function sendAndroidPushNotification($deviceRegistrationId,$messageText)
{   
    $authenticationID=googleAuthenticate(ANDROID_USERNAME,ANDROID_PASSWORD,ANDROID_SOURCE,ANDROID_SERVICE);
    $result= sendMessageToPhone($authenticationID,$deviceRegistrationId,ANDROID_MSGTYPE,$messageText);
