Can Thread survive App termination?

Question

If a .NET program creates and starts a System.Threading.ThreadPool thread, and then the program ends (either naturally or by crashing):

• Is it possible for the Thread to survive and carry on processing on its own?
• Is it possible that an App will look like it has terminated due to the main UI thread having ended, but for a background thread to carry on running invisibly?

Answer 1

No. By definition, if one of the threads of the process is still working, then it has not actually ended.
