Client Codes:

<script>
    $(function () {

        $.connection.hub.logging = true; 
        var notificationHub = $.connection.notificationHub;
    
          notificationHub.client.receiveNotification = function (message, userID, link) {

            showNotification('new message', message, link);
        };
        $.connection.hub.start(); 
        

    });


    $.connection.hub.disconnected(function () {
        setTimeout(function () {
            $.connection.hub.start();
        }, 5000); // Restart connection after 5 seconds.
    });

</script>




<script type="text/javascript">
        function notify(title,message,link) {
           
            var option = {
                body: message,
                dir: 'rtl',
                title:title,
                icon:'/Content/Images/notification.png',

            }

            var notify = new Notification(title, option);
            

            notify.onclick = function () {
                window.open(link, '_blank');
                notify.close();
            };

            

        }

        function showNotification(title, message, link) {

            if (!("Notification" in window)) {

                
                //alert('Your browser does not support Notification');

            } else if (Notification.permission === "granted") {

                notify(title, message, link);

            } else if (Notification.permission !== "denied") {

                Notification.requestPermission(function (permission) {

                    if (permission === "granted") {

                        notify(title, message, link);

                    }

                });

            }

        }
    </script>
