DotNetOpenAuth检测谷歌等获取请求

Question

使用Google，您可以像这样获取用户的电子邮件：

var fetch = new FetchRequest();
fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email);
request.AddExtension(fetch);

然后像这样回复：

var fetch = response.GetExtension<FetchResponse>();
string email = "";
if (fetch != null)
{
    email = fetch.GetAttributeValue(WellKnownAttributes.Contact.Email);
}

撰写提供者时，如何返回要求的值？

DotNetOpenAuth附带的OpenIdProviderWebForms示例包括返回用户属性。你看过了吗？
