Nlog 'one logger per class'

Question

I use NLog in my application. I have facade Logging that has private static Logger, so there is just one Logger in entire application. Like this:

 public class Logging
 {
        private static Logger _logger;
        //... constructors and methods
 }

But I read in Nlog documentation that 'one logger per class' approach is recommended, so you easily get point exception came from. So each class would have:

private static Logger _logger;

But that way every class would be coupled to NLog's Logger and LogManager class. What is best way to implement 'one logger per class' in this situation?

If you don't create a logger for each class, then you can't filter easily the messages in the config. Also if you use a helper class, then is still (indirect) coupled?

You can decouple NLog by using Common Logging. I has some up- and downsides, see faq.
