You can wrap ILog:
ILogInfo log = new LogInfo(LogManager.GetLogger(GetType()));
You can also write your own LogManager that calls the "new LogInfo" code for
you:
ILogInfo log = Company.Logging.LogManager.GetLogger(GetType());
You can set your custom properties on the specific LoggingEvent object instead
of on the thread itself:
// ILogInfo implementation
public void Info(int eventId, object message, System.Exception t)
{
if (this.IsInfoEnabled)
{
LoggingEvent loggingEvent = new LoggingEvent(ThisDeclaringType,
Logger.Repository, Logger.Name, Level.Info, message, t);
loggingEvent.Properties["EventID"] = eventId;
Logger.Log(loggingEvent);
}
}
That code was taken from:

Subject: RE: logging additional message-specific data with AdoNetAppender
Thanks for your input, Peter and William.
What I'm leaning towards is making a simple wrapper of LogManager and
ILog so that when I call GetLogger, I get a logger that supports the
following syntax, where LogInfo is any class that implements an ILogInfo
interface:
log.Debug(new LogInfo(1001, "Friendly message...", "Stack trace..."));
ILogInfo has two methods Set and Unset which are meant to set and unset
ThreadContext.Properties, along with a Message property. The logger's
Debug method, for example, is
public void Debug(ILogInfo info)
{
info.Set();
log.Debug(info.Message);
info.Unset();
}
One nice thing is that I can easily make new ILogInfo classes as
necessary, or create more constructors for the LogInfo classes.
References to the ThreadContext.Properties string keys are also
restricted to the ILogInfo classes they pertain to.

Chris,
We do exactly what you have indicated. In our programs we set the extra
columns with ThreadContext and GlobalContext properties. Works pretty
well for us. Here's our config for the appender:
<appender name="ADONetAppender_SqlServer"
