title: C# - How to use another project logging configuration into current project?
body: <p>I have 12 projects in my solution file. There are most Windows services (<code>ServiceProj_1, ServiceProj_2, ...</code>) and one project is of web application (<code>WebApp</code>). I use log4net for logging. <code>WebApp</code> and <code>ServiceProject_1, ServiceProj_2, ...</code> have log4net configuration into <code>web.config</code> and <code>app.config</code> files respectively. We have implemented a DMZ, so the <code>WebApp</code> is only exposed to the other people. Now there is a requirement to use logging of those windows service projects instead of <code>WebApp</code>. </p>
  
  <p>I have come to know that I can create a custom appender and make it possible. The catch is, there are lots of lines already written into <code>WebApp</code> to log a <code>LogMessage</code> into log file so we cannot touch those lines. </p>
  
  <p>I have no idea what to do and how to do. Need help.
  If the description is not understandable then please let me know I will try to explain more.</p>
