I think there may be a feature here that we can easily deliver on. Do we
think that setting arbitrary global params from the config file would be
useful?
Currently the ILoggerRepository has a Properties property which holds
key value pairs. This is designed to allow global settings to be read by
appenders etc... It is not possible to set values in this map from the
config file. It should be straight forward to add support if we decide
to do so.
The syntax in the config file would be something like:
<log4net>
<property>
<key value="foo" />
<data value="bar" />
</property>
...
</log4net>
Is this worth adding?
Will using the name 'Properties' for this get users confused with
ThreadContext.Properties?
Myself I don't see too many downsides to adding this feature, but
neither can I see many situations where it would actually help users.
Comments?
