subscribing to managed events from unmanaged applications - HOW?

[Matthias Krug]

Hi Gang!
Am I probably overlooking something?

I can use my .net application from external unmanaged (COM) applications
without problems. But I would also like to subscribe a method of the
COM-application to subscribe to an event in the .net application.

Surprisingly, I can subscribe to the event, but when this is fired,
nothing happens in the COM subscriber.

Can someone point me to a source of documentation please, about how to
achieve this (if possible...).

Thanks,
Matze
