I want to generate an anti-forgery token and it is checked every pages and every action to check and validate token but not regenerate token. the token is every time constant.

What I have tried:

i tried in every .cshtml page
put @Html.AntiForgeryToken()

example
in .cshtml page below code

@Html.AntiForgeryToken();
               @using (Html.BeginForm("ViewSearchAcknowledgementCase", "Manan", FormMethod.Post, new { @id = "Family", role = "form" }))
               {

                   <table id="ContentPlaceHolder1_tbldetail" cellspacing="15" width="97%">
                       <tr align="right">
                           <td colspan="4">
                               <span id="ContentPlaceHolder1_lblmandatory" style="color:Red;">*  Mandatory Field!</span>
                           </td>
                       </tr>

-------------------------------------------

and every action method i checked
[ValidateAntiForgeryToken]

and action method like below

[ValidateAntiForgeryToken]
     [HttpPost]
       public ActionResult ViewAcknowledgement()
       {
           M_Login ml = new M_Login();
           try
           {

A constant anti-forgery token would not provide any protection at all.

Perhaps if you update your question to explain the problem you're actually trying to solve, rather that asking for help with your chosen solution for that problem, somebody might be able to point you in the right direction.

The anti-forgery token needs to be inside the form.

@using (Html.BeginForm(...)
{
    @Html.AntiForgeryToken();
