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

Also, since I've seen this happen before, be careful with letting Visual Studio auto add usings for you. If you're not paying attention you may end up adding System.Web.Http instead of System.Web.Mvc.
