Logs that contain the most detailed messages. These messages may contain sensitive application data. /// These messages are disabled by default and should never be enabled in a production environment.
 Trace, /// 
Logs that are used for interactive investigation during development.  These logs should primarily contain /// information useful for debugging and have no long-term value.
 Debug, /// 
Logs that track the general flow of the application. These logs should have long-term value.
 Information, /// 
Logs that highlight an abnormal or unexpected event in the application flow, but do not otherwise cause the /// application execution to stop.
 Warning, /// 
Logs that highlight when the current flow of execution is stopped due to a failure. These should indicate a /// failure in the current activity, not an application-wide failure.
 Error, /// 
Logs that describe an unrecoverable application or system crash, or a catastrophic failure that requires /// immediate attention.
 Critical, /// 
Not used for writing log messages. Specifies that a logging category should not write any messages.
