Question

I have a thread pool and I use a library that if certain conditions are met to throw an exception. My question is if this runs out of the IDE, will the thread come to an halt or will the whole entire program come to a halt?

Answer 1

If the application is .Net 2+, an unhandled exception on a non-main thread will flatten the process.

You can configure this behavior using the app.config LegacyUnhandledExceptionPolicy setting, but I wouldn’t recommend this as it potentially masks serious bugs.

Update

If you wish to ignore the occasional timeout exception, consider placing your WebService call in a try\catch block and ignore the timeout exception:

try
{
    //Call WebService
}
catch(System.Net.WebException ex)
{
   //Ignore
}
