private IAuthenticationManager AuthenticationManager { get { return HttpContext.GetOwinContext().Authentication; } }
I get the error : 'System.Web.HttpContextBase' does not contain a definition for 'GetOwinContext' and no extension method 'GetOwinContext' accepting a first argument of type 'System.Web.HttpContextBase' could be found (are you missing a using directive or an assembly reference?) What might be wrong?
