Question

i am using dotnetopenid for implementing openid in my page i am facing a problem with myopenid as i am getting a null ClaimsResponse what i am doing in page load

OpenIdRelyingParty openid = new OpenIdRelyingParty();

    //fetching response.
    var response = openid.GetResponse();

    //checking response from openid provider.
    if (response != null)
    {
        switch (response.Status)
        {
            case AuthenticationStatus.Authenticated:
                // This is where you would look for any OpenID extension responses included
                // in the authentication assertion.
                //var claimsResponse = response.GetExtension<ClaimsResponse>();

                ClaimsResponse claimsResponse = response.GetExtension(typeof(ClaimsResponse)) as ClaimsResponse;
                string firstName = string.Empty;
                string lastName = string.Empty;
                string nickName = string.Empty;
                string parsedName = string.Empty;

                if (claimsResponse != null)
                {
                    userName = claimsResponse.FullName;
                    emailId = claimsResponse.Email;
                    nickName = claimsResponse.Nickname;
                    int insertOpenID = 0;

and on click of login button

protected void btnLogin_Click(object sender, EventArgs e)
{
     //BEGIN : code added by Niraj for OpenId.

    //checks for page validation.
    if (!this.Page.IsValid)
    {
        return; // don't login if custom validation failed.           
    }

    //Adds extension to the request and redirects the request to provider.
    try
    {
        using (OpenIdRelyingParty openid = new OpenIdRelyingParty())
        {
            IAuthenticationRequest request = openid.CreateRequest(this.txtOpenId.Text);
            // This is where you would add any OpenID extensions you wanted
            // to include in the authentication request.
            var fields = new ClaimsRequest();
            fields.Email = DemandLevel.Require;
            fields.FullName = DemandLevel.Require;
            fields.Nickname = DemandLevel.Require;

            request.AddExtension(fields);

            //request.AddExtension(new ClaimsRequest
            //{
            //    Email = DemandLevel.Require,
            //    FullName = DemandLevel.Require

            //});
            // Send your visitor to their Provider for authentication.
            request.RedirectToProvider();
        }
    }
    catch (ProtocolException objException)
    {
        ErrorLog.InsertException(objException);
    }
    //End.
