            On Windows platforms EventSource will deliver messages using Event Tracing for Windows (ETW) events.

             <summary>
             The LoggingEventSource is the bridge form all ILogger based logging to EventSource/EventListener logging.
            
             You turn this logging on by enabling the EvenSource called
            
                  Microsoft-Extensions-Logging
            
             When you enabled the EventSource, the EventLevel you set is translated in the obvious way to the level
             associated with the ILogger (thus Debug = verbose, Informational = Informational ... Critical == Critical)
            
             This allows you to filter by event level in a straighforward way.
            
             For finer control you can specify a EventSource Argument called
            
             FilterSpecs
            
             The FilterSpecs argument is a semicolon separated list of specifications.   Where each specification is
            
             SPEC =                          // empty spec, same as *
                  | NAME                     // Just a name the level is the default level
                  | NAME : LEVEL            // specifies level for a particular logger (can have a * suffix).
            
             Where Name is the name of a ILoggger (case matters), Name can have a * which acts as a wildcard
             AS A SUFFIX.   Thus Net* will match any loggers that start with the 'Net'.
            
             The LEVEL is a number or a LogLevel string. 0=Trace, 1=Debug, 2=Information, 3=Warning,  4=Error, Critical=5
             This speicifies the level for the associated pattern.  If the number is not specified, (first form
             of the specification) it is the default level for the EventSource.
            
             First match is used if a partciular name matches more than one pattern.
            
             In addition the level and FilterSpec argument, you can also set EventSource Keywords.  See the Keywords
             definition below, but basically you get to decide if you wish to have
            
               * Keywords.Message - You get the event with the data in parsed form.
               * Keywords.JsonMessage - you get an event with the data in parse form but as a JSON blob (not broken up by argument ...)
               * Keywords.FormattedMessage - you get an event with the data formatted as a string
            
             It is expected that you will turn only one of these keywords on at a time, but you can turn them all on (and get
             the same data logged three different ways.
            
             Example Usage
            
             This example shows how to use an EventListener to get ILogging information
            
             class MyEventListener : EventListener {
                 protected override void OnEventSourceCreated(EventSource eventSource) {
                     if (eventSource.Name == "Microsoft-Extensions-Logging") {
                         // initialize a string, string dictionary of arguments to pass to the EventSource.
                         // Turn on loggers matching App* to Information, everything else (*) is the default level (which is EventLevel.Error)
                         var args = new Dictionary&lt;string, string&gt;() { { "FilterSpecs", "App*:Information;*" } };
                         // Set the default level (verbosity) to Error, and only ask for the formatted messages in this case.
                         EnableEvents(eventSource, EventLevel.Error, LoggingEventSource.Keywords.FormattedMessage, args);
                     }
                 }
                 protected override void OnEventWritten(EventWrittenEventArgs eventData) {
                     // Look for the formatted message event, which has the following argument layout (as defined in the LoggingEventSource.
                     // FormattedMessage(LogLevel Level, int FactoryID, string LoggerName, string EventId, string FormattedMessage);
                     if (eventData.EventName == "FormattedMessage")
                         Console.WriteLine("Logger {0}: {1}", eventData.Payload[2], eventData.Payload[4]);
                 }
             }
