Log4Net Issue with .Net 4.0
I have looked for a "fix" to my issue for a few days not and have gotten nowhere. Basically what is happening is that I have an application that writes to a database and sends an email via log4Net.
Here is where I initialize my log object:
private static readonly log4net.ILog log;
#endregion
static PTSentryService()
{
// Initialize log4net.
log4net.Config.XmlConfigurator.Configure();
log = log4net.LogManager.GetLogger(typeof(PTSentryService));
}
I then use the LogHelper class to grab the configuration information, below is what I have in my Web.Config:
<log4net>

What occurs is that all the properties in the ILog
object (isErrorEnabled, etc) are all false. I know this is due to the config not being loaded properly, but this is a copy paste job from a .Net 3.5 project that I know works. Are there changes that I need to make to accommodate 4.0?
Any info would be excellent, thanks!
What you may want to do is try simplifying your config to see if it's a certain appender or other config value that is causing this. Maybe take out your database appender and see if it works.
Also I encountered this issue before when my references folder was jacked up. You can check the SO article out here: log4net not working in dll
One other thing that I usually see is the logger actually being declared before the call to configure. I doubt that this matters but just throwing stuff out there.
private static readonly log4net.ILog log = log = log4net.LogManager.GetLogger(typeof(PTSentryService));
static PTSentryService()
{
// Initialize log4net.
log4net.Config.XmlConfigurator.Configure();
}
Edit:
In addition to this you may want to turn on log4net logging to see if you see anything fishy.
