Slin.Masking.NLog provides the extension methods which will make it be bit easier to use Slin.Masking in NLog. The EventPropertiesMaskerLayoutRenderer with name 'event-properties-masker' was added. Example: ``` var logger = LogManager .Setup(setupBuilder: (setupBuilder) => setupBuilder.UseMasking("masking.json")) .GetCurrentClassLogger(); ```
