La solicitud de OAuth Consumer para el token de ServiceProvider devuelve InternalServerError

Question

Estoy jugando con DevDefined.OAuth - una implementación de OAuth consumidor y proveedor para .Net http://code.google.com/p/devdefined-tools/wiki/OAuth y al iniciar el proyecto ExampleConsumerSite después de configurar los puntos finales del servicio en mi servidor web IIS 7, recibo la siguiente error:

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.

He notado que el parámetro GET de oauth_token está vacío. Al rastrear esto, el origen del error es de la línea 12 de la página Default.aspx.cs:

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);
}

Aunque no estoy seguro de si esto tiene que ver con la configuración de los puntos finales del servicio, pero estoy ejecutando el proyecto del consumidor desde VS2008 y hospedando el servicio en IIS. Por favor consejo.

Trabajando ahora. El error se debió a que la página RequestToken.aspx en el OAuthChannel no heredó la clase correcta detrás, por lo que cuando el sitio del consumidor realizó una solicitud de un token que resultó en un error interno del servidor en el lado del Proveedor de Servicios.
