Hi,

I'm creating a ManualResetEvent in one AppDomain and then passing it
to a second AppDomain. (WaitHandle derives from MarshalByRefObject.)

If I call WaitOne() on my wait handle's remoting proxy, it works just
fine. If I pass the proxy to WaitHandle.WaitAny(), however, I get an
ArgumentNullException (see below).

The ManualResetEvent is obviously remoting okay because WaitOne()
works. Does anyone know why I can't seemt to use the same object
reference in a call to WaitHandle.WaitAny()?

Thanks,
- Lee

Hello Lee,

No, sorry - there seems to be something rather weird going wrong with
serialization, judging from your stack trace. I'd suggest you might want
to post this to microsoft.public.dotnet.framework.remoting, in case some
expert can help with a reference to a known problem.

Okay - thanks.
