Html.AntiForgeryToken() threw exception

Question

_{Thursday, November 7, 2013 4:59 AM}

Hi,

We are trying to integrate ADFS to a MVC4 application in which CSRF is implemented using Html.AntiForgeryToken().

We are getting the error

A claim of type 'http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier' or 'http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider' was not present on the provided ClaimsIdentity. To enable anti-forgery token support with claims-based authentication, please verify that the configured claims provider is providing both of these claims on the ClaimsIdentity instances it generates. If the configured claims provider instead uses a different claim type as a unique identifier, it can be configured by setting the static property AntiForgeryConfig.UniqueClaimTypeIdentifier

We are trying to add AntiForgeryConfig.UniqueClaimTypeIdentifier in global.asax in application_start event.

But we are not  able to find Antiforgeryconfig class in either System.web.webpages / system.web.mvc/system.web.helpers.

Is there any way to fix this issue?

Are you sure you are referencing the latest assemblies? A couple of troubleshooting steps:

1. Try updating your references using NuGet and update to the latest Visual Studio Web Tools update.

2. Create a new MVC 4 project from scratch, then copy your existing code into the new project. You should have the updated helpers then.
