  How to stop an application

  Jan 12, 2016 09:12 AM|iLens|LINK

  I have an application where each user's interaction with the site takes many pages and lasts up to 10 minutes. It runs 24/7 in its own apppool.

  As the user progresses through the pages, I store the data they provide in the session state.

  I have disabled automatic recycling to avoid the session state getting destroyed mid-interaction, and I've tried to schedule a recycle at a specific time (4am on Tuesdays) with a timer in the Application.Start event. I've tried many approaches from different forums - currently HttpRuntime.UnloadAppDomain(). The Application.OnEnd and  Application.Start events fire and the code runs, but the "old" version of the app seems to continue running. Eventually the site goes non-responsive.

  How can I programatically cause the app to stop and then restart as if the application pool had recycled?

  If you want to set duration in the app pool, this would be recommended and hopefully helpful too:
  
  https://www.iis.net/configreference/system.applicationhost/applicationpools/add/recycling?_e_pi_=7%2CPAGE_ID10%2C6936134746
  
  And to do it programmatically, follow the below links:

  Helping others is to provide help to yourself. Mark as answer, if the solution helps.

  Hi,iLens

  The following code examples add an application pool named Contoso to IIS 7 server, then set the application pool to daily recycle at 3:00 A.M.

     private static void Main()
     {
        using (ServerManager serverManager = new ServerManager())
        {
           Configuration config = serverManager.GetApplicationHostConfiguration();
           ConfigurationSection applicationPoolsSection = config.GetSection("system.applicationHost/applicationPools");
           ConfigurationElementCollection applicationPoolsCollection = applicationPoolsSection.GetCollection();
           ConfigurationElement addElement = applicationPoolsCollection.CreateElement("add");
           addElement["name"] = @"Contoso";
           ConfigurationElement recyclingElement = addElement.GetChildElement("recycling");
           ConfigurationElement periodicRestartElement = recyclingElement.GetChildElement("periodicRestart");
           ConfigurationElementCollection scheduleCollection = periodicRestartElement.GetCollection("schedule");
           ConfigurationElement addElement1 = scheduleCollection.CreateElement("add");
           addElement1["value"] = TimeSpan.Parse("03:00:00");
           scheduleCollection.Add(addElement1);
           applicationPoolsCollection.Add(addElement);
           serverManager.CommitChanges();
        }
     }
