ActionExecutedContext.Canceled might be established to true When the motion execution was brief-circuited by Yet another filter.
determined by which motion system is referred to as. For example, an app may need action approaches for both equally API endpoints and for sights/HTML. The API endpoints could return mistake information as JSON, whilst the check out-based mostly steps could return an mistake web site as HTML.
As soon as the MVC middleware takes in excess of, it phone calls into several different filters at various points within just its action invocation pipeline.

This doc relates to Razor Internet pages, API controllers, and controllers with sights. Filters Do not operate instantly with Razor components. A filter can only indirectly have an effect on a component when:
Utilizing authentication logic along with filters can help in verifying the identities on the buyers that try to obtain the secured resources.
In ASP.NET MVC, controllers define motion methods that typically Have a very 1-to-one partnership with doable consumer interactions, but from time to time you ought to conduct logic either just before an action method is called or after an motion approach runs.
