Visual Studio 2015混合C#/ C++调试器启动速度极慢

Question

我有一个混合的托管/本机桌面解决方案.开始调试时,需要大约一分钟(!)才能启动,并立即进入调试对象.

几个信息:

1)在主线程上打破'立即'=在此堆栈上的中断:

>   kernel32.dll!GetFullPathNameW() Unknown
    mscorlib.ni.dll!00007ffaa4f51310()  Unknown
    [Managed to Native Transition]  
    mscorlib.dll!System.IO.PathHelper.GetFullPathName() Unknown
    mscorlib.dll!System.IO.Path.NormalizePath(string path = "D:\\cwx_tfs\\718_High_risk_branch\\Application\\Bin\\Debug\\CathWorksUI.exe.Config", bool fullCheck, int maxPathLength = 260, bool expandShortPaths = true)    Unknown
    mscorlib.dll!System.IO.Path.GetFullPathInternal(string path)    Unknown
    mscorlib.dll!System.AppDomainSetup.NormalizePath(string path, bool useAppBase)  Unknown
    mscorlib.dll!System.AppDomainSetup.VerifyDir(string dir, bool normalize)    Unknown
    System.Configuration.dll!System.Configuration.ClientConfigPaths.ClientConfigPaths(string exePath = null, bool includeUserConfig)    Unknown
    System.Configuration.dll!System.Configuration.ClientConfigPaths.GetPaths(string exePath, bool includeUserConfig = false)    Unknown
    System.Configuration.dll!System.Configuration.ClientConfigurationHost.GetStreamName(string configPath)  Unknown
    System.Configuration.dll!System.Configuration.ClientConfigurationHost.IsAppConfigHttp.get() Unknown
    System.Configuration.dll!System.Configuration.ClientConfigurationSystem.ClientConfigurationSystem() Unknown
    System.Configuration.dll!System.Configuration.ConfigurationManager.EnsureConfigurationSystem()  Unknown
    System.Configuration.dll!System.Configuration.ConfigurationManager.PrepareConfigSystem()    Unknown
    System.Configuration.dll!System.Configuration.ConfigurationManager.GetSection(string sectionName = "system.diagnostics")    Unknown
    System.dll!System.Configuration.PrivilegedConfigurationManager.GetSection(string sectionName)   Unknown
    System.dll!System.Diagnostics.DiagnosticsConfiguration.Initialize() Unknown
    System.dll!System.Diagnostics.DiagnosticsConfiguration.Sources.get()    Unknown
    System.dll!System.Diagnostics.TraceSource.Initialize()  Unknown
    System.dll!System.Diagnostics.TraceSource.Switch.get()  Unknown
    WindowsBase.dll!System.Diagnostics.PresentationTraceSources.CreateTraceSource(string sourceName)    Unknown
    WindowsBase.dll!System.Diagnostics.PresentationTraceSources.DependencyPropertySource.get()  Unknown
    WindowsBase.dll!MS.Internal.AvTrace.Initialize()    Unknown
    WindowsBase.dll!MS.Internal.TraceDependencyProperty.TraceDependencyProperty()   Unknown
    ...

2)我看到一个我不熟悉的主题,从ntdll.dll!DbgUiRemoteBreakin() 中断位置开始ntdll.dll!RtlUserThreadStart.

3)在生成的进程msvsmon('Visual studio 2015远程调试器')中有大约60秒的高CPU活动.在使用WPA进行检查时,我发现在mscordbi.dll上花费了不成比例的时间!ShimStackWalk.特别是在这个堆栈:

我什么都不做,只是经常桌面调试.我也在/ safemode中复制了这个,所以它可能不是扩展问题.调试相同代码的其他计算机上不会发生这种情况,因此它不是一些奇特的代码问题.VS重新安装后仍然存在.我可能以某种方式使用非默认调试引擎吗？任何其他想法都将非常受欢迎.

4)刚刚发现,如果我取消选中"启用本机代码调试",则60秒延迟消失.它是混合调试引擎特有的.

5)刚刚在VS ActivityLog.xml中看到了这个:

  <entry>
    <record>126</record>
    <time>2016/07/13 12:24:32.728</time>
    <type>Error</type>
    <source>Microsoft.VisualStudio.CommonIDE.ExtensibilityHosting.VsShellComponentModelHost</source>
    <description>Still unable to load MEF component DLL: Could not load file or assembly &apos;DebuggerPackage.dll&apos; or one of its dependencies. The system cannot find the file specified.</description>
    <path>C:\PROGRAM FILES (X86)\MICROSOFT VISUAL STUDIO 14.0\COMMON7\IDE\EXTENSIONS\MICROSOFT\DEBUGGING TOOLS FOR WINDOWS\DEBUGGERPACKAGE\DebuggerPackage.dll</path>
  </entry>

听起来很相关.我该如何解决？
