@Ani have already answered your question. Although I don’t agree that unhandled exceptions in threads should terminate applications. Using threads usually means that you have some kind of server application. Bringing it down could result in a lot of angry users.
I’ve written a small piece about proper exception handling: https://coderr.io/exception-handling
You should always catch exceptions for threads. I usually use the following pattern:
void ThreadMethod(object state)
{
try
{
ActualWorkerMethod();
}
catch (Exception err)
{
_logger.Error("Unhandled exception in thread.", err);
}
}
void ActualWorkerMethod()
{
// do something clever
}
It’s a whole lot easier to find thread methods that doesn’t handle exceptions properly by moving the logic into a seperate method and just keep the try/catch block in the thread method.
