Hi.

I have read the MS documentation about COM+ but I find myself very
confused about some concepts. My main doubt is about synchronization
and causality. It seems that these elements are related, but how
exactly?
Any help from you will be great!!

Thanks,
Robert Scheer

When you use synchronization in you component and a component's method is
called, an activity is created, and a causality id is associated with the
caller thread.
If the subsequent calls to the method, doesn't have the same causality id of
the currently executing thread inside the current activity, the call is
blocked and it waits until
the currently executing thread finishes.
