input: [Category] Faults [Description] The solution demonstrates IDesign fault handling framework. The class ErrorHandlerHelper automates implementing IErrorHandler: it promotes all exceptions to matching fault exceptions if found in fault 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. The attribute ErrorHandlerBehaviorAttribute wraps the use of ErrorHandlerHelper and automatically installs the error handler by attaching it to all dispatchers. [Last Updated] 2/24/2007 [Title]
