To activate this filter, we initially must include this filter with the assistance of ConfigureService and then, we can utilize the reference of this filter possibly in the controller class or action strategy to be a ServiceFilter.
Filters assist both equally synchronous and asynchronous implementations through various interface definitions.
The filter pipeline may be shorter-circuited by placing The end result assets within the ResourceExecutingContext parameter furnished to the filter technique. For instance, the subsequent Resource filter helps prevent the rest of the pipeline from executing:
Authorization filters are used to implement authentication and authorization for controller steps. For instance, the Authorize filter is undoubtedly an illustration of an Authorization filter.
