DotNetOpenAuth; AsActionResult does not work

Question

extention method

AsActionResult()

does not work. I get string "DotNetOpenAuth.Messaging.OutgoingWebResponseActionResult" to response instead of redirect to provider. namespace

using DotNetOpenAuth.Messaging;

is included. Where is problem?

[ADDED] my code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

using DotNetOpenAuth.Messaging;
using DotNetOpenAuth.OpenId;
using DotNetOpenAuth.OpenId.RelyingParty;
using System.Web.Security;
    public class UserController : Controller
    {
        private static OpenIdRelyingParty openIdProvider = new OpenIdRelyingParty();

        public ActionResult Authenticate(string userOpenId)
        {
            // Ответ с сайта провайдера.
            IAuthenticationResponse response = openIdProvider.GetResponse();

            // response равен null, если запроса на OpenID провайдер мы не делали.
            if (response == null)
            {
                Identifier id;
                // Пытаемся распарсить OpenID клиента.
                if (Identifier.TryParse(userOpenId, out id))
                {
                    try
                    {
                        // Делаем редирект на сайт провайдера OpenID
                        return
                            openIdProvider

I found solution - need to check web.config and be sure, that all libraries compiled to .NET 3.0. Correct keys:

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
      <dependentAssembly xmlns="">
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="2.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

incorrect:

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0" />
      </dependentAssembly>
      <dependentAssembly xmlns="">
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="2.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
