Now, let us rewrite the previous illustration employing IAsyncResultFilter. We need to carry out the IAsyncResultFilter interface and wishes to supply the mandatory asynchronous dealing with for the result execution and article-execution activities. Create a course file named CustomResultFilter.cs and after that duplicate and paste the next code:

To avoid avoidable processing, consider to use filters only the place They're seriously needed, Otherwise then steer clear of working with them.

Since securing APIs is its have topic, I’m deliberately leaving that outside the house the scope of this sample.

Filters which have been executed as characteristics and included straight to controller courses or action strategies are not able to have constructor dependencies supplied by dependency injection (DI).

Filters help both synchronous and asynchronous implementations by way of distinctive interface definitions.
