1. Basic log4net configuration. You need to let log4net know where to put the data. First open AssemblyInfo.cs. Add following line. assembly: log4net.Config.XmlConfigurator(Watch=true) This way log4net will know that it can look for configuration in the default application config file. Next, let’s open the config (App.config) and add following.
  2. With this configuration I get a new log every minute which is OK. The only problem is the name of the logs. The file name of the first log is as expected: Log-01.43.log.
  3. Mar 20, 2012  Configuration Attributes: The log4net environment is fully configurable programmatically. However, it is far more flexible to configure log4net using configuration files. Currently, configuration files are written in XML. The configuration file can be configured programmatically.
  4. Dec 29, 2010  As a result, the video Application Logging in C#: The log4net tutorial was created. I hope you enjoy it, as well as the rest of this article. There are a three parts to log4net. There is the configuration, the setup, and the call. The configuration is typically done in the app.config or web.config file. We will go over this in depth.
  5. For full details see the SDK Reference entry: log4net.Appender.RollingFileAppender. The RollingFileAppender builds on the FileAppender and has the same options as that appender. The following example shows how to configure the RollingFileAppender to write to the file log.txt.
  6. Aug 07, 2012  Logging with Log4Net in C#. Aug 7, 2012.net c# configuration example log4net tutorial. In the end I decided that the only way to fix the problem is to write a general tutorial on Log4Net configuration myself. Is specific for the RollingFileAppender, and specifies the criteria type for when it should 'roll.

May 06, 2016  Simple log4net setup in a console application. Log4net; c#.NET; There’s not much to this post, other than a very minimal setup for a console application using log4net for logging, with some nice basics, such as: red highlighting of errors; yellow highlighting of warnings; logs are written to both console and file.

I have following configuration:

And the following code in global.asax:

For the tag file in configuration above. I have tried C:my foldermylog.log as well as what is seen above mylog.log

However, I do not see this file generated anywhere and there are no exceptions.

Environment: VS 2013 ASP.Net VB. Running via Debug menu. When I run IISExpress is started by VS2013 and site runs. but no log is seen.

I have tried various combinations for the file tag but nothing works.

Can someone help please?

This used to work for me (I've switched to the lighter and better configurable NLog), log rolled daily, was written in a subfolder named 'Logs' under the app's path.

And

This logged to loglog4net.log in the application directory (i.e. where my code is )
