You will want to do two things. First, to request offline_access, you need to change the Javascript login function to request offline access as follows. This is in the Views/Home/Index.aspx.

Next, to get the access token, you just do the following in action after the user is authenticated:

    public ActionResult Profile()
    {
        var app = new FacebookApp();
        if (app.Session == null)
        {
            // The user isnt logged in to Facebook
            // send them to the home page
            return RedirectToAction("Index");
        }
    // Read current access token:
        var accessToken = app.Session.AccessToken;

        // Get the user info from the Graph API
        dynamic me = app.Api("/me");
        ViewData["FirstName"] = me.first_name;
        ViewData["LastName"] = me.last_name;

        return View();
    }
