Exception ManagementThe .NET architecture guide says that "Exceptions need to be serializble in
order to flow upstream accross tiers". Why? Cant we simply throw excpetions to the calling code even if it is in a diffent component in a differnt layer in a differnt machine on the newtork? I think it is basiccly passing exceptions. -- Regards Ginny That's exactly what that sentence means. You CAN just pass an exception
between layers without having to serialize it. However, if you wanted to pass an exception through a web service, you'd need to serialzie it.
