Interface ILogger

Defines the logging service.

Namespace:System.Dynamic.ExpandoObject

Assembly:Umbraco.Core.dll

Syntax

public interface ILogger

Remarks

Message templates in logging methods follow the Message Templates specification available at https://messagetemplates.org/ in order to support structured logging.

Implementations must ensure that they support these templates. Note that the specification includes support for traditional C# numeric placeholders.

For instance, "Processed {Input} in {Time}ms."
