c# - DotNetOpenAuth OpenID 提供商 "Sequence contains more than one element"

Question

我在使用 DNOA 3.4.3 实现我的 OpenID 提供程序时遇到了问题。在我也需要 AX 支持之前，一切都非常顺利。我在网络配置中设置了 AXFetchAsSregTransform，正如 Andrew 在 http://groups.google.com/group/dotnetopenid/browse_thread/thread/5629a24c0a7e8d99 推荐的那样.这样做导致我在我的 decide.aspx 页面上出现异常“序列包含多个元素”，但是，我一直无法克服它。

以下行抛出异常:
编辑:奇怪的是，这不再是引发错误的行。 SendResponse() 现在触发异常

ClaimsRequest requestedFields = ProviderEndpoint.PendingRequest.GetExtension();

ProviderEndpoint.SendResponse()

有没有想过为什么会这样？任何帮助将不胜感激!

导致错误的日志如下:

Answer 1

糟糕。您在 DotNetOpenAuth 中发现了一个错误。

修复 checkin v3.2 as 7cea654和 v3.4 as bd7c148 .您可以在 tomorrow's build 中获得修复.
