What happens when a .NET thread throws an exception?

Question

We have an interface IPoller for which we have various implementations. We have a process that will take an IPoller and start it in a separate thread. I\'m trying to come

Answer 1

You should catch the exception at the method you use at the top of the thread, and do the logging from there.

An unhandled exception (at the top of a thread) will (in 2.0 onwards) kill your process. Not good.

i.e. whatever method you pass to Thread.Start (etc) should have a try/catch, and do something useful in the catch (logging, perhaps graceful shutdown, etc).

To achieve this, you could use:

• static logging methods
• captured variables into the delegate (as an anonymous method)
• expose your method on an instance that already knows about the logger
