Two assemblies using same Log4Net framework

[Peter <pe...@circle-consulting.co.nz>]

Hi

My main VB.NET application uses sets up and configures Log4Net.  It calls two 
or three other assemblies and I want to "pass a reference" to the main app's 
Log4Net instance to those assemblies so they log messages into the same log 
file and respect the same configuration settings.  Is it correct to do this:

In the main app I have the following method call to my assembly:

  SetLog(mLog.Logger.Repository)

Where "mLog" implements the ILog interface.

In the assembly the SetLog method is:

  Public Sub SetLog(ByVal Repository As log4net.Repository.ILoggerRepository)

    log4net.Config.BasicConfigurator.Configure(Repository)

    mLog = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod
().DeclaringType)
   
   End Sub

This seems to work OK but I'm unsure if it's a good thing to pass Repository's 
between assemblies in this way.

Any and all advice would be appreciated.

The main application should configure log4net. The other libraries should just create logging statements. You don't need to pass the repository between applications.
