Hinweise

The primary method for logging is the Log method. All events logged using this method will be subject to filtering by the LoggingOptions object. However, you achieve certain performance gains by conditioning the calls to Log based on whether logging is enabled, which is done by checking the Enabled status. This enables you to save the time it would take to compose the arguments and the method call overhead.
