How do I use NLog in a C# application?

To use NLog in a C# application, first, install the NLog package via NuGet. Then, configure NLog in your appsettings.json or NLog.config file.

What are the basic configurations I need to set up?

You need to define targets (where logs will be sent, like files or databases) and rules (which specify what to log and at what level).

Can you give me an example of logging to a file?

Sure! In your NLog.config, you can add a file target like this: <target name="file" xsi:type="File" fileName="logs/app.log" /> and a rule like <logger name="*" minlevel="Debug" writeTo="file" />.

How can I log exceptions?

You can log exceptions using logger.Error(ex) where ex is your exception object. This will capture the stack trace and message.
