我正在使用 WCF 服务和 Azure 进行游戏。
我有几个 WCF 服务在 Azure 上成功运行，这个特定的服务一直在正常运行，直到我决定在不同的（现有的）云服务下重新部署它。
我在我的 VS 解决方案中将其从云服务 X 的角色中删除，并将其添加到另一个云服务角色。我发布了，当我发布时，我收到异常错误“未处理的异常：Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironmentException”。有人告诉我，该服务不断被回收。
此消息显示在此 WCF 服务所在的实例下的 Azure 管理门户中。我已经在它自己的云服务和具有实例的服务下尝试过它。
审查了有关该问题的少量文章（http://blogs.msdn.com/b/davidmcg/archive/2011/03/10/diagnosticmonitor-roleenvironmentexception-was-unhandled.aspx）和（http://www.microsofttranslator。 com/bv.aspx?from=&to=en&a=http%3A%2F%2Fpul.se%2FBlog-Post-Error-RoleEnvironmentException-was-unhandled_Video-ptFrIOhJU6%2ClWCxfMvJiNbE )
远程到实例上，我在事件查看器中有以下内容：
Application: WaIISHost.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironmentException
Stack:
at Microsoft.WindowsAzure.ServiceRuntime.Implementation.Loader.RoleRuntimeBridge.<InitializeRole>b__0()
at System.Threading.ExecutionContext.RunInternal(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
at System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
at System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object)
at System.Threading.ThreadHelper.ThreadStart()
我还发现：
Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironmentException: error
at Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment.GetLocalResource(String localResourceName)
at WCFServiceDataTransfer.AzureLocalStorageTraceListener.GetLogDirectory()
at WCFServiceDataTransfer.WebRole.OnStart()
但这是 AzureLocalStorageTraceListener 中自动生成的代码。
我怎样才能找到这个问题的根源？
