How do you create SeqAppender programatically in log4net? - log4net

Question

I tried the following code based on other responses on how to add custom appender programmatically. I do see log messages appear on the console, but I do not see them in a locally running Seq server. I verified the Seq URL was set http://localhost:5341/. I also tried a hosted version of Seq with API Key to see if I could catch anything being set via Fiddler, but nothing is sent. What am I missing?
public static void SetLevel(string loggerName, string levelName)
{
ILog log = LogManager.GetLogger(loggerName);
Logger l = (Logger)log.Logger;
l.Level = l.Hierarchy.LevelMap[levelName];
}
// Add an appender to a logger
public static void AddAppender(string loggerName, IAppender appender)
{
ILog log = LogManager.GetLogger(loggerName);
Logger l = (Logger)log.Logger;
l.AddAppender(appender);
l.Repository.Configured = true;
}
// Create a new file appender
public static IAppender CreateSeqAppender(string name)
{
var seqAppender = new SeqAppender();
seqAppender.ServerUrl = ConfigurationManager.AppSettings["Seq:Url"];
var seqApiKey = ConfigurationManager.AppSettings["Seq:ApiKey"];
if (seqApiKey != null)
{
seqAppender.ApiKey = seqApiKey;
}
PatternLayout patternLayout = new PatternLayout();
var LOG_PATTERN = "%d [%t] %-5p %m%n";
patternLayout.ConversionPattern = LOG_PATTERN;
patternLayout.ActivateOptions();
seqAppender.Name = name;
seqAppender.BufferSize = 1;
seqAppender.Layout = patternLayout;
seqAppender.ActivateOptions();
return seqAppender;
}
static void Main()
{
BasicConfigurator.Configure();
// In order to set the level for a logger and add an appender reference you
// can then use the following calls:
SetLevel("Log4net.MainForm", "ALL");
AddAppender("Log4net.MainForm", CreateSeqAppender("SeqAppender"));
//BasicConfigurator.Configure();
var logger = LogManager.GetLogger("MyLogger");
logger.Info("This is a test log message");
}

After a bit more investigation I figured out how to get this to work. Instead the code in AddAppender above I just did the following:
var root = ((Hierarchy)LogManager.GetRepository()).Root;
root.AddAppender(CreateSeqAppender());
Hopefully, this helps someone else out.
