using log4net on my project within a self-hosted WCF application z

1. Add reference to log4net.dll to our console service host project (our application entry point)

2. Add the following line to the above project‘s AssemblyInfo.cs file (allows a custom log4net config file to be specified, which log4net will "watch" for updates. Quick, but maybe a bit dirty..)

   [assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

3. // LOG 4 net config
   [assembly:log4net.Config.XmlConfigurator(Watch=true)]

5. Add log4net.config file to console project and copy it to the output directory (file properties: "Copy to Output Directory")

6. Add log4net.dll reference to all projects where you require logging

7. Declare the logger as private static member of the classes where you need logging:

    private static readonly log4net.ILog Logger = 
    log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

8. 
   

   Log where required:

9. Logger.Info("Starting console service host");
