log4net Configurable Custom Properties

log4net is a great facility to create logs. When it comes to extending it, it’s good as well. To add a custom property to a custom appender that can be configured from configuration XML file is so simple, that it even looks suspicious.

Custom appender class has to define a read/write property publicly exposed. That’s it. Let’s say that property name is “ApplicationVersion”. To configuration looks like this:

<ApplicationVersion value="1.2.0.0"/>
