I have the same problem as below:
ASP.NET MVC 3 ValidateRequest(false) not working with FormCollection
I have tried to add a reference to the System.Web.Helpers dll, and added a using System.Web.Helpers in my controller, but it wont accept Unvalidated() as a method under Request. Im using .NET 4 and MVC 3 RC.

Method 1
The Unvalidated() extension method is defined in the System.Web.WebPages.dll assembly, not System.Web.Helpers.dll (but still in the System.Web.Helpers namespace)
Sorry for the confusion.
