Overriding AuthorizeCore in custom Authorize attribute results in “no suitable method found to override” error

Question

I\'m trying to build custom AuthorizeAttribute, so in my Core project (a class library) I have this code:

using System;
using System.Web;
using System.Web.Mv         


        

Answer 1

I had this error too. It turned out that Visual Studio had added to my ActionFilter by default:

using System.Web.Http;

Even when I added System.Web.Mvc I still got the error. Commenting out System.Web.Http and just using System.Web.Mvc seems to solve the problem for me.

Hoping this might help someone!
