Troubleshooting anti-forgery token problems

Question

I have a form post that consistently gives me an anti-forgery token error.

Here is my form:

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


        

Answer 1

Another possible thing to check which has caused this error for me: I had two @Html.AntiForgeryToken() in one of my forms.

Once that was removed problem went away.
