U4-6522 - 'System.Web.Mvc.HtmlHelper.AntiForgeryToken(string)' is obsolete: 'This method is deprecated.

I've a project build in ASP.Net 4.0 using Umbraco version 6.1.6. Here I'm using Contour, when I build my solution it is throwing "Error 5 'System.Web.Mvc.HtmlHelper.AntiForgeryToken(string)' is obsolete: 'This method is deprecated. Use the AntiForgeryToken() method instead. To specify custom data to be embedded within the token, use the static AntiForgeryConfig.AdditionalDataProvider property'." error in "ContourForm.cshtml" and compilation fails.

I've also upgraded the Contour version to 3.0.26, but it doesn't work.

I dig a lot into this and created a new empty test web application and configured Contour in that, then it worked.So, I copied all the files related to Contour from test to actual application, but again it failed.

Can any one help reason why this is not working with actual project.
