IResultFilter and IAsyncResultFilter instances are not executed in cases where an authorization filter or resource filter short-circuits the request to prevent execution of the action. IResultFilter. IResultFilter and IAsyncResultFilter implementations are also not executed in cases where an exception filter handles an exception by producing an action result.
