Exception Policies

The following are some “Exception Policies” from Patterns & Practices:

• Exceptions of type ApplicationException should be logged
• Exceptions of type SqlClientException should be caught and wrapped with an exception of type DataLayerException and re-thrown
• Exceptions of type SecurityException should caught and replaced with an AccessDeniedException which will be thrown
