ServiceProviderからのトークンに対するOAuthコンシューマー要求は、InternalServerErrorを返します

Question

.Net http://code.google.com/p/devdefined-tools/wiki/OAuth およびIIS 7 Webサーバーでサービスエンドポイントを構成した後にExampleConsumerSiteプロジェクトを起動すると、次のエラー：

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Exception: Request for uri: http://localhost:8080/RequestToken.aspx?oauth_callback=oob&oauth_nonce=94efde0b-dd45-4cee-8253-7496cef0b877&oauth_consumer_key=key&oauth_signature_method=PLAINTEXT&oauth_timestamp=1252512419&oauth_version=1.0&oauth_token=&oauth_signature=secret%2526 failed.
status code: InternalServerError

oauth_token GETパラメーターが空であることに気付きました。これをトレースすると、エラーの原因はDefault.aspx.csページの12行目です：

IToken requestToken = session.GetRequestToken();

protected void oauthRequest_Click(object sender, EventArgs e)
{
  OAuthSession session = CreateSession();

  IToken requestToken = session.GetRequestToken();

  if (string.IsNullOrEmpty(requestToken.Token))
  {
    throw new Exception("The request token was null or empty");
  }

  Session[requestToken.Token] = requestToken;

  string callBackUrl = "http://localhost:" + HttpContext.Current.Request.Url.Port + "/Callback.aspx";

  string authorizationUrl = session.GetUserAuthorizationUrlForToken(requestToken, callBackUrl);

  Response.Redirect(authorizationUrl, true);
}

これがサービスエンドポイントの構成に関係しているかどうかはわかりませんが、VS2008からコンシューマプロジェクトを実行し、IISでサービスをホストしています。アドバイスしてください。

今作業中です。エラーは、OAuthChannelのページRequestToken.aspxが正しいクラスを継承していないために発生しました。そのため、コンシューマサイトがトークンをリクエストして、ServiceProvider側で内部サーバーエラーが発生しました。
