IIS 7 integration mode vs. Classic Mode

IIS is a pipeline and a filter, and ASP. NET is also a pipeline and a filter. Simply don't wrap it around. It's just the integration mode.

 

Foreground thread vs background thread

Thread. isbackground = true, ApplicationProgramTo exit, you must wait for all foreground threads to exit, and do not have to wait for background threads.

 

Worker thread vs. Io thread

Threadpool itself is for performance, and the distinction between the two threads is also for performance. threadpool provides different treatment for the two threads.
