How to detect a shutdown and run code before shutdown execution in MVC .NET

Question

I have a web server cluster (windows 2008) that collects usage data from clients. The servers all batch the data and send after a certain time or amount of data. The problem is we are using AWS auto-scaling, and the machine can be shut down at any time. I would like to detect a shutdown event and send the usage data to the database before the application is killed. Does anyone know if this is possible?

I would say, you can perform these tasks (in code/ yourself) when your server goes back up.

Otherwise look here http://social.technet.microsoft.com/Forums/windowsserver/en-US/bd8ea190-9bf4-4915-8ed9-96ee5d6f336a/when-are-windows-server-20032008-shutdown-scripts-run-in-the-shutdown-process

The server does not go back up, when they are shutdown they are terminated. I've trying to shut the site down in a batch file as you suggest, but I'm running into timing issues http://stackoverflow.com/questions/17733989/halt-batch-file-until-website-stop-is-complete – JoshNaro Jul 22 '13 at 17:04

You can subscribe to this event and perform your logic before the application is shutdown.

Application.Current.Exit +=DoSomething;

Tried that. It works if the website is stopped manually, but not on a Windows shutdown. May need to modify the Windows shutdown policy so that it stops the site during a shutdown, as suggested by T.S.'s link. – JoshNaro Jul 18 '13 at 13:59

WebActivator is NuGet package designed to clean up application Start and Shutdown registrations.

This will register your MyStaticClass.Start() and MyStaticClass.Shutdown() methods:

[assembly: WebActivator.PostApplicationStartMethod(typeof(MyStaticClass), "Start")]
[assembly: WebActivator.ApplicationShutdownMethod(typeof(MyStaticClass), "Shutdown")]
