Hi Bob
There is no reason to expect a delay like that. There are ways to minimize collection delay times when designing an interactive managed application. For example:
-avoid using finalizers. Objects in the finalization queue tend to hang around longer and require more overhead when collecting
-avoid forcing generation 2 collections by calling GC.Collect(). Gen2 collections are expensive performance-wise.
-if possible, use concurrent GC (on multi-proc machines). This setting allows generation 2 collections to occur while the program is running
See these articles for more information:

You might also want to monitor the microsoft.public.dotnet.framework.performance newsgroup.
If you have any other questions, let me know
Thanks

There are some in our group that are afraid that .NET will freeze the
application for up to 15 seconds doing garbage collection when the system
must respond within 1 second of a button press. From the analysis I have
done to date, I don't see that happening. I'm just trying to come up with
anything that would appease their concerns.
Thanks!

No, there are no GC events you can monitor to find out when a GC will
occur or has occurred.
What kind of critical event are you concerned out?
Thanks
