Projects / NLog


NLog is a .NET logging library designed with simplicity and flexibility in mind. With NLog you can process diagnostic messages emitted from any .NET language, augment them with contextual information, format them according to your preference, and send them to one or more targets. The API (application programming interface) is similar to log4net, and the configuration is very simple. NLog uses a routing table while log4net uses a logger hierarchy with attachable ppenders. This makes NLog's configuration very easy to read and maintain.
