using NLog; class MyClass { private static readonly Logger logger = LogManager.GetCurrentClassLogger(); public void DoSomething() { logger.Trace("Entering DoSomething method..."); // do something... logger.Trace("Exiting DoSomething method..."); } }In this example, we first import the NLog namespace and create a static instance of the logger using the `GetCurrentClassLogger` method. We then use the logger to log messages at the trace level before and after executing a method. The NLog Trace logger is part of the NLog framework package. To use it, you need to add the `NLog` package reference to your project.
