Microsoft Azure实例部署中的RoleEnvironmentException

Question

我正在玩一个带有WCF服务和Azure的游戏.

我有几个WCF服务在Azure上成功运行,这个特定服务一直运行正常,直到我决定在不同的(现有)Cloud Service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,当我这样做时,我收到异常错误"Unhandled Exception:Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironmentException".我被告知这项服务一直在循环使用.

此消息显示在此WCF服务所在的实例下的Azure管理门户中.我已经尝试了它自己的云服务和实例服务.

查看了有关该问题的文章(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)

远程登录到实例,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.

我怎样才能找到问题的根源？

好的,这就解决了这个问题.我将以下内容添加到Imports结束标记下的ServiceDefinition.csdef文件中.它根本不存在,一旦我添加了下面的内容并且发布了实例就可以启动了.

使用1.8版

<LocalResources>
   <LocalStorage name="WCFServiceDataTransfer.svclog" sizeInMB="1000" cleanOnRoleRecycle="false" />
</LocalResources>
