 ### Custom Attributes
 
 As an alternative to specifying the subject and type through log configuration or properties, you can decorate your code at design time with the `[EventGridSubject]` and `[EventGridType]` Attributes.

The Serilog log event called within the context of a method or class decorated with either attribute, will use those values when submitting the event. The first ones closest to the log event call in the stack, win.
