Description

would be useful an override like this
ILog.Debug(Func<string> messageDelegate);

callable as
log..Debug(()=> MyTimeExpensiveMethod);

This is to prevent boiled code as
if(log.IsDebugEnable)
{
log..Debug(MyTimeExpensiveMethod());
}

Log4Net can call the messageDelegate only when really needed.

If you want stay in NET2.0 you can create a specific delegate
public delegate string MessageDelegate;

Btw, IMO, the new version should target directly .NET3.5.
