Nicko,
Thanks for your response. When I use the LogFileAppender it logs the
property values when remoting is used. However when a buffering appender
is used e.g. adonetappender, the property does not get stored. There are
no internal errors thrown as well. While debugging I found that the MDC
gets cleared in the BufferingSkeleton.cs at the following code when I
use remoting.

if (m_bufferSize <=3D 1)
{
 // Only send the event if we are in non lossy mode or the event is a
triggering event
if ((!m_lossy) ||	(m_evaluator !=3D null &&
m_evaluator.IsTriggeringEvent(loggingEvent)) || (m_lossyEvaluator !=3D
null && m_lossyEvaluator.IsTriggeringEvent(loggingEvent)))
	{
	 if (m_eventMustBeFixed)
					{
		// Derive class expects fixed events
		loggingEvent.Fix =3D this.Fix;  //// ***THIS IS WHERE THE
MDC VALUE IS CLEARED IN REMOTING**////
					}

// Not buffering events, send immediatly
	SendBuffer(new LoggingEvent[] { loggingEvent } );
				}

I have set the buffersize to 1. So when SendBuffer is called when
remoting is used loggingEvent object does not have the property values
in it.
However when I use the adonetappender directly I don't get this problem.


The two properties I am setting are "User" and "Client" in my example.
Here is config file I use on the client side. I have commented out the
one of the appenders in the client side based on whether I do remoting
or direct adonetappender.

Here's the server side config. I have both LogFileAppender and
adonetappender configured. As I said before all the property values show
up correctly on the logfileappender during use of remoting.

What do your 2 log4net configuration files look like?

In your receiving app what happens if you add a FileAppender that would
log the property values, for example:

<appender name=3D"LogFileAppender" =
type=3D"log4net.Appender.FileAppender">
  <file value=3D"log-file.txt" />
  <layout type=3D"log4net.Layout.PatternLayout">
    <conversionPattern value=3D"%d %-5p %c %X{YourPropertyName} - %m%n" =
/>
  </layout>
</appender>=20
