NDC and MDC fields logged as (null)
I am using the 1.2.10. The NDC and MDC fields are logged in file as (null)
if they are no value. Are they supposed to just log empty string if there
are no values?
Thanks.

Hmmm, I'm getting confused. Assuming we are dealing with this snippet
of code:
using(ThreadContext.Stacks["NDC"].Push("Hello"))
{
log.Info("World");
}
and a layout pattern of "%message %ndc" you should see this output:
World Hello

I'm running .NET 2.0 and I don't have a value for it, either.

%property always contains log4net:HostName.

The NDC is implemented with a ThreadContextStack which internally uses
a Stack to store values. If you don't push anything onto the NDC, the
Stack remains empty with a Count of zero.
The NDC has a value when log messages are written inside of its scope:
using(ThreadContext.Stacks["NDC"].Push("Hello"))
{
log.Info("World");
}

Hmm, you mean the NDC doesn't always have a value? Then when is the NDC not
empty? I had assumed it always had a value of some sort, like a thread id.

What should the value of the empty NDC be? null seems like an ok
canidate doesn't it?

I was wondering why the value is null at all. Shouldn't the NDC have a value?

The default string value for null items is "(null)". The default string
value for items that are not available is "NOT AVAILABLE". These can be
changed by setting the log4net.NullText and log4net.NotAvailableText
appSettings keys.

I'm seeing the same problem with the same version running on .Net 2.0. Anyone
else seeing this problem? Is this a known bug?
