openid - 使用 DotNetOpenAuth 时，Azure 开发结构因 SocketException 崩溃

Question

我正在尝试使用 DotNetOpenAuth OpenID 身份验证在 Windows Azure Dev Fabric 下运行 ASP.NET MVC 2 网站。

当我进行身份验证时，Azure Dev 结构本身反复崩溃 (dfloadbalancer.exe)。

是否有任何解决方法可以解决允许使用 Azure Dev Fabric 和 DotNetOpenAuth 的问题？

MSDN 似乎对同一问题有一些 old discussion，但已被放弃。

崩溃前的最新日志消息是:

Answer 1

我在使用以下语句时遇到了这个问题:

return request.RedirectingResponse.AsActionResult();

我通过将行更改为来纠正此问题:

string location = request.RedirectingResponse.Headers["Location"];
return Redirect(location);

由于我不知道的原因，这解决了错误并允许我回到正题，而无需对我的开发环境进行任何特殊更改。
