The required anti-forgery form field "__RequestVerificationToken" is not present Error in user Registration

You have [ValidateAntiForgeryToken] attribute before your action. You also should add @Html.AntiForgeryToken() in your form.

In my case, I had this in my web.config:

<httpCookies requireSSL="true" />

But my project was set to not use SSL. Commenting out that line or setting up the project to always use SSL solved it.

Like this:

The Controller

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult MethodName(FormCollection formCollection)
{
     ...
     Code Block
     ...
}

The View:

@using(Html.BeginForm())
{
     @Html.AntiForgeryToken()
     <input name="..." type="text" />
     // rest
}
