[solved ]The required anti-forgery cookie "__RequestVerificationToken" is not present., someone asked me to explain?

We need to add [ValidateAntiForgeryToken] attribute before our action. And also should add @Html.AntiForgeryToken() in our form. 

We don't need to use [ValidateAntiForgeryToken] attribute for the GET actions. Use POST request from page which was generated by our application. This attack called cross site request forgeries. When we use It will prevent from forgeries.



public ActionResult Login(UserLogin userlogin)
   <!--/ Check Login -->

The View: 

@using (@Html.BeginForm("Login", "Admin", FormMethod.Post))
     <input name="..." type="text" />
