Writing a log entry

Component: NServiceBus
NuGet Package NServiceBus (5.x)
Standard support for version 5.x of NServiceBus has expired. For more information see our Support Policy.

Set up a single static field to an ILog in the classes, and then use it in all methods:

public class ClassUsingLogging
{
    static ILog log = LogManager.GetLogger<ClassUsingLogging>();

    public void SomeMethod()
    {
        log.Debug("Something interesting happened.");
    }
}
When writing to a logger, ensure the log level is set to a value that will result in that log entry being written. For example, when calling .Debug(..) ensure that the log level is set to DEBUG. See Change settings via configuration.
Since LogManager.GetLogger(..); is an expensive call, it is important that the field is static so that the call happens only once per class and has the best possible performance.
