azure - 升级到 sdk 2.2 后无法调试 azure 解决方案。解决方案无需调试即可正常运行。可以将调试器附加到正在运行的模拟器

Question

我有一个包含 2 个角色的云解决方案:1 个 Web 角色、1 个辅助角色。该解决方案最近从 sdk 2.1 升级，运行良好。

如果我在没有调试的情况下运行解决方案，例如按 Ctrl-F5，模拟器将启动并且角色将按要求运行。我什至可以将调试器附加到正在运行的角色，尽管那时我已经错过了所有角色初始化。

如果我使用调试(例如 F5)运行，模拟器将启动； worker 角色陷入“角色状态繁忙”，网络角色陷入“角色不健康”， Visual Studio 变得无响应，需要任务管理器来终止。在 VS 中，下部 RHS 中的部署动画继续运行。即使我注释掉 RoleEntryPoint 的所有 OnStart 和 Run 重写，也会发生同样的情况。无论应用程序生命周期有多早，我都无法命中任何断点，因此我非常确定这是模拟器基础设施/与调试器问题。

我当前正在使用程序集绑定(bind)登录运行，并且没有注意到任何异常情况。我检查了一遍，所有项目中的sdk引用以及所有依赖都已经升级了。

如果我在启用调试和角色诊断的情况下运行，即使其他所有内容都被卡住，我也会将与配置更新相关的条目添加到输出中。例如:

    [Diagnostics]: Checking for configuration updates 10/01/2014 

我正在寻找新的调查线索，已经用尽了我能想到的一切。顺便说一句，这不是特定于机器的，我已经在几台机器上进行了测试，它们都表现出这种行为。

编辑:我应该注意到，即使使用 2.2 sdk，其他云解决方案也是可调试的。

更新:我在日志中收到以下内容:

Answer 1

我们的项目也有同样的问题。微软错误报告在这里:

https://connect.microsoft.com/VisualStudio/feedback/details/817341/vs-debugger-cannot-attach-to-azurewebrole-with-more-then-one-iis-endpointbinding-when-using-iis-reproducable#

在此链接中还有一种解决此问题的(肮脏的)方法。希望微软尽快解决这个问题。
