Question

我从下面的callstack中得到这个未处理的异常，但是我不知道为什么它会以这种方式对我失败...（虽然对于我运行它的方式可能有些特别，是的...）< / p>

“跨应用程序域的远程调用失败，在程序集'System.Xml.Linq中的类型'System.Xml.Linq.XElement'，版本= 4.0.0.0，文化=中立，PublicKeyToken = b77a5c561934e089'未标记为可序列化”< / p>

失败的电话来自

         at Microsoft.ServiceHosting.Tools.MSBuildTasks.PackageCreator.CreateServiceApplicationPackage(String serviceRdFilePath, String processedServiceDefinitionFile, FileStream packageStream, Dictionary`2 namedStreams, Dictionary`2 rolesDictionary)

当我检查被走私的消息时，我看到argsToSerialize包含一些MemoryStreams和

+       [0x00000000]    {[Kernel, Microsoft.ServiceHosting.Tools.Internal.SimpleServiceModel.Role]} System.Collections.Generic.KeyValuePair<string,Microsoft.ServiceHosting.Tools.Internal.SimpleServiceModel.Role>

Microsoft.ServiceHosting.Tools.Internal.SimpleServiceModel.Role标记为[Serializable]。

看起来序列化可能正在序列化类型的属性 Microsoft.ServiceHosting.Tools.Internal.SimpleServiceModel.RoleEnvironment

其中包含XElement ... aha。这是不是因为XElement不应该在[Serializable]类中？但我想知道当我从命令行运行cspack时这个问题怎么没有重现？我该如何解决这个问题？

Answer 1

我与在Azure SDK上工作的人取得了联系。他告诉我在SDK 2.5中遇到的bug在SDK 2.5.1中修复了，万岁！我还没有测试过它。

如何使用SimpleServiceModel.Role解决此序列化问题？
