当我将 DotNetOpenAuth dll 放入我的 /bin 目录时，我的应用程序将无法使用以下堆栈跟踪运行。有人对这个图书馆有任何经验吗？我浏览了他们的文档并怀疑我没有正确部署它。我的 Web 应用程序应该在我的本地计算机上完全信任地运行，因此不清楚它要求的哪些权限无法获得。

谢谢！汤姆

奇怪的是，我发现解决方案与此有关。

应用程序池标识有一个称为加载用户配置文件的属性。当此值为 false 时，您可能会收到上面显示的错误。要解决此问题，请打开 IIS 管理器并导航到您的应用程序池标识。您将在“高级设置”窗口中找到该设置。将其更改为真。

我发现当我将它设置为 true 时，库又开始工作了。当我将其翻转回 false 时，即使在服务重新启动和应用程序池回收之后，它仍然可以继续工作。所以，奇怪的是，现在一切似乎都很好。

看起来代码访问安全不认为 DotNetOpenAuth 是完全信任加载的。实际上，它只需要中等信任，但这里是 DotNetOpenAuth 请求的最低权限列表：

[assembly: SecurityPermission(SecurityAction.RequestMinimum, Execution = true)]
[assembly: WebPermission(SecurityAction.RequestMinimum, ConnectPattern = @"http://.*")]
[assembly: WebPermission(SecurityAction.RequestMinimum, ConnectPattern = @"https://.*")]

某些中等信任配置中可能缺少第二对，但是如果您以完全信任的方式运行，这应该不是问题。

尝试<trust level="Full"/>在其部分中添加到您的 web.config 文件，<system.web>看看是否有帮助，或者生成有助于缩小问题范围的错误。
