.NET MVC5 Sessions not ending

I am fairly new to .NET and am having the following issue. I am working on an internal application that uses Window Authentication. I need to create a temporary object and store it in the database for the duration of the session. Once the session ends, I no longer need that object.

I have code in Session_start that creates the object, and code in Session_end that destroys it.

    protected void Session_Start(Object sender, EventArgs e)
    {
        MyDbContext db = new MyDbContext ();
        MyObject o = new MyObject () { Temporary = 1 };
        db.MyObjects.Add(o);
        db.SaveChanges();
        HttpContext.Current.Session.Add("my_object_id", o.ID);
    }

    protected void Session_End(Object sender, EventArgs e)
    {
        MyDbContext db = new MyDbContext ();
        try
        {
            MyObject o = db.MyObjects.Find(HttpContext.Current.Session["my_object_id"]);
            db.MyObjects.Remove(o);
            db.SaveChanges();
        }
        catch (Exception)
        {
            //do nothing
        }
    }

I also have the following xml entry in my config file

    <sessionState mode="InProc" timeout="30" />

My issue is that these objects are being created but never destroyed. Currently we are hosting our application on a dev server, as well as running it locally with Visual Studios internal iisexpress server.

I will be trying to add some sort of logging to see if session_end is ever being called. This application will not have any sort of logout mechanism(Internal app with windows authentication).

I am not sure if I am even doing this right. Any help would be appreciated.

Make sure that the application pool timeout is larger than the session timeout. Otherwise the application pool will be recycled before the Session_End method is invoked (if your site do not have many visitors).

You can find the setting here:
