Mvc4How does on replace ValidateAntiForgeryTokenAttribute.Salt Property with AntiForgeryConfig.AdditionalDataProvider ??? ‎

Question

I updated to mvc 4 and got this error that :
ValidateAntiForgeryTokenAttribute.Salt Property (System
[ObsoleteAttribute("The 'Salt' property is
deprecated. To specify custom data to be embedded within the token, use the
static AntiForgeryConfig.AdditionalDataProvider ...
How does this replace ValidateAntiForgeryTokenWrapperAttribute :
FilterAttribute, IAuthorizationFilter which is used an attribute on a class and
is used for validation from an ajax posting involving
__RequestVerificationToken: getAntiForgeryToken????
Do I just get of all the classes that have the
[ValidateAntiForgeryTokenWrapper] attribute applied to them and some derived class from IAntiForgeryAdditionalDataProvider interface.
I have not found one example are solution that said what to do or how to
change the classes that [ValidateAntiForgeryTokenWrapper]  applied to them, and
replace them whith this  AntiForgeryConfig.AdditionalDataProvider. Any advice
Below is the ValidateAntiForgeryTokenWrapperAttribute  class used. It is applied as an attribute to a class. The error is thrown where Salt = salt line of code. So how exactly do I replace that line of code by AntiForgeryConfig.AdditionalDataProvider?
Please do not give me links to explanation or link to where someone tried some other way which does use AntiForgeryConfig.AdditionalDataProvider which usually causes another half million errors. I am looking just how to replace the Salt and suggested. Source
code to and a project is what I am looking for to show how this works
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method,
AllowMultiple = false, Inherited = true)]
    public class
ValidateAntiForgeryTokenWrapperAttribute : FilterAttribute,
IAuthorizationFilter
        private readonly
ValidateAntiForgeryTokenAttribute _validator;
        private readonly AcceptVerbsAttribute _verbs;
        public ValidateAntiForgeryTokenWrapperAttribute(HttpVerbs verbs) :
this(verbs, null)
        public ValidateAntiForgeryTokenWrapperAttribute(HttpVerbs verbs,
string salt)
            this._verbs = new
AcceptVerbsAttribute(verbs);
AntiForgeryConfig.AdditionalDataProvider = salt;
            this._validator
= new ValidateAntiForgeryTokenAttribute()
                    Salt = salt
AntiForgeryConfig.AdditionalDataProvider = salt

in the mvc forum I was redirected to the sign in sheet again. That Microsoft for sucking the big one as usual
