What's the secret to getting ClaimsResponse working with DotNetOpenId?

Question

What's the secret to getting ClaimsResponse working with DotNetOpenId?

For example, in this bit of code (from Scott Hanselman's blog) the ClaimsResponse object should have lots of nice little things like 'nickname' and 'email address', but the ClaimsResponse object itself is 'null':

 OpenIdRelyingParty openid = new OpenIdRelyingParty();  
 if (openid.Response != null)  
 {  
    // Stage 3: OpenID Provider sending assertion response  
    switch (openid.Response.Status)  
    {  
       case AuthenticationStatus.Authenticated:  
          ClaimsResponse fetch = openid.Response.GetExtension(typeof(ClaimsResponse)) as ClaimsResponse;  
          string nick = fetch.Nickname;  
          string homepage = openid.Response.ClaimedIdentifier;  
          string email = fetch.Email;  
          string comment = Session["pendingComment"] as string;  
          string entryId = Session["pendingEntryId"] as string;  
          if (String.IsNullOrEmpty(comment) == false && String.IsNullOrEmpty(entryId) == false)  
          {  
             AddNewComment(nick, email, homepage, comment, entryId, true);  
          }  
          break;  
    }  
 }  

At first, I thought it was because I wasn't redirecting to the provider with a 'ClaimsRequest' ... but using this code to redirect to the OpenId provider still doesn't help:

OpenIdRelyingParty openid = new OpenIdRelyingParty();  
IAuthenticationRequest req = openid.CreateRequest(openid_identifier.Text);  
ClaimsRequest fetch = new ClaimsRequest();  
fetch.Email = DemandLevel.Require;  
fetch.Nickname = DemandLevel.Require;  
req.AddExtension(fetch);  
req.RedirectToProvider(); 

What am I doing wrong? Or have other devs experienced the same pain?

I dont know if you have solved the problem or not, but I found the solution after many hours of struggle. Actually you need to change your web.config file to claim email and fullname here is web.config which works for me. I downloaded it from nerddinner project. Actually I copied everything except web.config and I was not getting the email field. So later on I found something else is wrong. I copied web.config from nerddinner project and everything was working.

here is the file, if you dont want to go to nerddinner project.
