multithreading - Parallel event handling in C#

Question

I’m developing a module that has to handle many events coming from an external system. I’ve to use a third party class providing an event (OnNewMessage) passing some parameters as input and two as output, each event require a bunch of time in order to be processed. I’d like to serve these events in a parallel way, in order to avoid blocking the caller and to process multiple request in parallel.

Here an example of my code:

void Init()
{
   provider.OnNewMessage += new OnMessageEventHandler(processEvent);
}

void processEvent(string xml, int …, out string resultXML, out string description)
{
   ...
}

Which is the best approach to do this in C# 3.5?

Thanks

I would use a queue to store the events, and then consume that queue from a bounch of thread from the thread pool.
