Answer 1

You can create a model for this view, for example:

public class PackageIndexModel()
{
    public List<Package> Packages { get; set; }
    public int NotificationCount { get; set; }
    public int FeedbackCount { get; set; }
}

and you can return this

var obj = new PackageIndexModel() { Packages = db.packages.ToList(), NotificationCount = notificationCounter(), FeedbackCount = feedbackCounter() };
return View(obj);

Or you could just set that object on a TempData:

TempData["Notifications"] = obj;

And in your _Layout.cshtml:

@{
    if (TempData["Notifications"] != null)
    {
        foreach (var notification in ((PackageIndexModel)TempData["Notification"]).Packages)
        {
            <script type="text/javascript">
                jQuery(document).ready(function () {
                    alert('@notification.Message');
                });
            </script>
        }

        TempData["Notifications"] = null;
    }
}

EDIT: I think the second example is cleaner, because on don't have to receive your notifications on every view you create.
