ICoreLogger Interface
A common interface to core logging functionality
Properties
CorrelationID CorrelationID[Get]
The correlation ID allows the tracing of an operation from beginning to end. It can be linked to other IDs to form a full chain when it branches out or moves to other domains. If not supplied explicitly while logging, it will be inherited from the thread storage or a new one will be generated if none exist.

newCorrelationId
The source correlation ID (eg. child operation).
rootCorrelationId
The target correlation ID (eg. root operation).
void Log
( CorrelationID correlationId,

Parameters
correlationId
The correlation ID.
verbosity
The verbosity of the logging.
message
The message to log.
parameters
The parameter
void Log
( CorrelationID correlationId,
VLoggerVerbosity verbosity,
Exception exception,
ErrorCode errorCode,
string message,
