Re: Thread won't start?

Tech-Archive recommends: Fix windows errors by optimizing your registry

not quite true.

the lifetime of a thread is tied to the process. if the hosting appdomain is
unloaded, an abort request is sent to the thread by the clr

if you use create thread as the example did, a new process thread is
created, a thread is not taken from the clr thread pool. you need to use clr
thread pool api to do this.
