Exception Shielding

One of the very important aspects of a robust service architecture is the concept of exception shielding. In short, exception shielding deals with the explicit boundaries between a service and its consumers (clients), and how exceptions raised within the service are handled and presented to the client. Although conceptually simple, it's not a straightforward topic when it comes to implementation. Microsoft has posted a good introduction to the concept. Shortly I'll be posting more on the topic as my own solution takes form.
