我是天蓝色开发的新手。我有一个 azure 应用程序在本地运行良好，但在 azure 上部署时会抛出 SEHException。使用 Visual Studio 发布时，活动日志显示这两个实例都停留在回收中。我使用远程桌面连接到一个实例，并尝试使用该实例上的浏览器访问应用程序。

我收到以下异常。

Exception: System.Runtime.InteropServices.SEHException: External component has thrown an exception

StackTrace:
[SEHException (0x80004005): External component has thrown an exception.]

它表明 RoleEnvironment.GetLocalResource 导致错误。还有一个问题，为什么我在调用 RoleEnvironment.GetConfigurationSettingValue("MYKEY") 时会收到 SEHException？在 RoleEnvironment.GetConfigurationSettingValue 上得到相同的异常。但是错误出现在本地环境中。在这里，应用程序在本地环境中运行良好，但在 azure 上失败。可能是什么原因？

这是我的 ServiceDefinition 和 ServiceConfiguration.Cloud 文件
