deploying AntiforgeryToken Error

Question

I am working on an ASP.NET MVC application on my local machine using the Visual Studio 2012 built in IISExpress. After a significant progress I decided to make it available

Answer 1

One thing I noticed is that this error could be caused by having multiple @Html.AntiForgeryToken() pieces of code on the page. I had 2 on my page and once I removed the second one, this error went away.
