Setting preloadEnabled and startMode

gistfile1.cs

    public class WebRole : RoleEntryPoint
    {
        public override void Run()
        {
            using (var serverManager = new ServerManager())
            {
                var mainSite = serverManager.Sites[RoleEnvironment.CurrentRoleInstance.Id + "_Web"];
                var mainApplication = mainSite.Applications["/"];
                mainApplication["preloadEnabled"] = true;

                var mainApplicationPool = serverManager.ApplicationPools[mainApplication.ApplicationPoolName];
                mainApplicationPool["startMode"] = "AlwaysRunning";
                
                serverManager.CommitChanges();
            }

            base.Run();
        }

        public override bool OnStart()
        {
            // For information on handling configuration changes
            // see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.

            return base.OnStart();
        }
    }

We do have it in the WebRole, but still seeing the application restarting:
