You’re wrong. That’s the MVC namespace which does pass AuthorzationContext. The question specifically states Web API which uses System.Web.Http.AuthorizeAttribute. If you look at the documentation, that does take an instance of HttpActionContext as the parameter to OnAuthorization.

target2: WebApi -> HttpActionContext
target2: MVC -> AuthorizationContext
