Hi all


When .NET fires and event, does the event handler execute under a new
thread, or does it execute under the primary application thread?

Basically if I have events firing, do the event handlers themselves need to
spawn need threads, or can I safely assume the event handler is already
running under a new thread?

Thanks!

The event handler runs in the same thread as the code that raises the event.
No thread is created. The event handler is just a function called.

If you want to run something in a new thread each time the event handler is
called, you must start the thread on you own.

Thank you - That clears it up :-)

Or run the delegate asycronously using BeginInvoke - in that case, the
method will be called on a thread from the thread pool.

If I do so, I'll have to call EndInvoke correct?

I'm using Threadpool.QueueUserWorkItem to process each call in it's own
thread.
