What happens to a IIS started thread after a redeploy?

Question

My doubt is the following:

• I have a page (aspx) which starts a new thread. I'm wonder to know what happens to the process of that thread if I undeploy the Application, or if I update the Application with a new version of the thread source code.

IIS wait the started thread to finish, throws a exception or just stop abruptly without exceptions?

Thank you

If you redeploy the application with web.config the worker process used by your application pool will get recycled. Even if you change the web.config without deploying it'll restart (recycle) the worker process.

Worker process recycle means your application will restart again. It will wait for the running processes to complete.

But, if you just deploy your .aspx code it will not recycle the worker process.

Also read this at SO about worker process recycling.
