input: [Category] Faults [Description] The solution demonstrates IDesign fault handling framework, this time on the client side. The CallbackErrorHandlerAttribute is applied on the callback client-side class. It installs an error handler on all callback dispatchers. The error handler promotes all exceptions to matching fault exceptions if found in the fault contract of the callback contract, and it logs the exception to a dedicated logbook service. The log entry contains a detailed stack and context dump. The solution also contains the logbook viewer application. [Last Updated] 2/24/2007 [Title]
