Question

我正在使用WCF服务调试类库，该服务使用WCF测试客户端和Visual Studio 2013 Ultimate调试器在Windows 8.1上使用已安装的Azure SDK 2.4。该库是使用AnyCPU编译的。调用RoleEnvironment.IsAvailable时发生异常。以下是详细信息：

  Message=The type initializer for 'Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment'   threw an exception.
  ...
  InnerException: System.TypeInitializationException
       Message=The type initializer for '<Module>' threw an exception.

                      at <CrtImplementationDetails>.DoCallBackInDefaultDomain(IntPtr function, Void* cookie)
                      at <CrtImplementationDetails>.DefaultDomain.Initialize()
                      at <CrtImplementationDetails>.LanguageSupport.InitializeDefaultAppDomain(LanguageSupport* )
                      at <CrtImplementationDetails>.LanguageSupport._Initialize(LanguageSupport* )
                      at <CrtImplementationDetails>.LanguageSupport.Initialize(LanguageSupport* )

启用非托管代码调试没有给我任何新信息。我尝试安装最新版本的Azure SDK，将useLegacyV2RuntimeActivationPolicy="true"标志添加到配置文件，但这些都没有帮助。从我的测试项目调用的相同库代码无异常地工作。同时使用x86和x64测试设置。调试文件夹似乎包含完全相同的ServiceRuntime dll版本。

导致此异常的原因是什么，以及我如何修复它？

它看起来像是与应用域相关的新错误。我从MSTest访问RoleEnvironment时看到了它，它使用应用程序域来隔离测试。这是堆栈跟踪：

对于在Visual Studio Team Services（VSTS）中尝试执行测试任务时遇到此问题的任何其他人，请在构建中包含自定义设置文件，并在任务定义上设置路径位置。制作并设置ForcedLegacyMode attribute = true。这解决了我的问题。

<?xml version="1.0" encoding="utf-8"?>
<RunSettings>
      <TargetFrameworkVersion>Framework45</TargetFrameworkVersion>  
  <MSTest>
     <ForcedLegacyMode>true</ForcedLegacyMode> 
  </MSTest>
</RunSettings>

有关Visual Studio测试文件的其他设置和属性的文档，请参阅https://msdn.microsoft.com/library/jj635153.aspx?f=255&MSPPError=-2147217396。
