How to handle all unhandled exceptions when using Task Parallel Library?

Question

I'm using the TPL (Task Parallel Library) in .NET 4.0. I want to be able to centralize the handling logic of all unhandled exceptions by using the Thread.GetDomain().UnhandledException event. However, in my application, the event is never fired for threads started with TPL code, e.g. Task.Factory.StartNew(...). The event is indeed fired if I use something like new Thread(threadStart).Start().

This MSDN article suggests to use Task#Wait() to catch the AggregateException when working with TPL, but that is not I want because it is not "centralized" enough a mechanism.

Does anyone experience same problem at all or is it just me? Do you have any solution for this?

Seems like there's no built-in way to handle this (and no answer to this question after almost 2 weeks). I already rolled out some custom code to take care of this. The solution description is pretty lengthy, so I've posted in my blog. Refer to this post if you're interested.

Update 5/7/2010: I've found a better solution, making use of task continuation. The code is posted here.
