c# - Is it possible to use async/await in MVC 4 AuthorizeAttribute?

Question

The only override I see exposed on MVC's AuthorizeAttribute is public override void OnAuthorization( AuthorizationContext filterContext ) which is not suitable for use with async/await because it doesn't return a Task. Is there another way to create an AuthorizeAttribute in MVC that allows the use of async/await?

Answer 1

ASP.NET MVC today does not support asynchronous filters. Please vote.

However, ASP.NET "vNext", announced at TechEd this week, will support asynchronous filters for MVC.
