问题描述

我正在尝试将我的 Windows Phone 8 应用程序移植到 Windows 10.我能够构建我的应用程序.当我尝试在移动模拟器上的 Release x86 中部署我的应用程序时，它失败了给出以下信息:

I am trying to port my Windows Phone 8 app to Windows 10. I am able to build my app. When I try to deploy my app in Release x86 on a Mobile emulator, it fails & gives the following msg:

无法从 Microsoft 符号服务器下载 ntdll.dll 的符号.异常字符串和调用堆栈可能无法正常工作.请确保您有网络连接，然后重试

即使我尝试在发布模式下运行我的应用程序，我也不知道为什么 VS-2015 很费力地下载这些调试符号.
经过在互联网上的一些搜索，我已经完成了这些，但我仍然看到问题:

Even though I am trying to run my app in Release mode, I am not sure why VS-2015 is tyring to download these debugging symbols.
After a bit of searching on the internet, I have done these, yet I continue to see the issue:

我已经从这里下载了 Windows-10 中可用的所有必要符号:https://msdn.microsoft.com/en-us/windows/hardware/gg463028.aspx 到 C:\Symbols
在 VS Tools->Options->Debugging->Server 中，我为 Symbol file).pdb) 位置创建了两个条目.一个指向Microsoft Symbol Servers，另一个指向C:\Symbols
机器有互联网连接，所以连接没有问题，正如错误消息所指出的那样.
我已将环境变量 _NT_SYMBOL_PATH 设置为 SRVc:\symbolshttp://msdl.microsoft.com/download/symbols

I have already downloaded, all necessary symbols available from Windows-10 from here: https://msdn.microsoft.com/en-us/windows/hardware/gg463028.aspx to C:\Symbols
In VS Tools->Options->Debugging->Server, I have created two entries for Symbol file).pdb) locations. One points to Microsoft Symbol Servers and the other to C:\Symbols
The machine has internet connection, so there is no problem with the connection as the error message points to.
I have set environment var _NT_SYMBOL_PATH to SRVc:\symbolshttp://msdl.microsoft.com/download/symbols

有人遇到过这个问题吗?

推荐答案

这是版本 10.0.10586.122 (th2_release_inmarket.160222-1549) 中 x86 NTDLL.dll 的已知问题.Microsoft 符号服务器上缺少该文件:

this is a known issue with the x86 NTDLL.dll in Version 10.0.10586.122 (th2_release_inmarket.160222-1549). The file is missing on the Microsoft symbol server:

SYMSRV:  Successfully closed the connection to the Server.
SYMSRV:  d:\sym\dl\wn\wntdll.pdb\39814CFBD1A74710A3F8FCAD3D7EC5661\wntdll.pdb not found
SYMSRV:  https://msdl.microsoft.com/download/symbols/wntdll.pdb/39814CFBD1A74710A3F8FCAD3D7EC5661/wntdll.pdb not found
DBGHELP: wntdll.pdb - file not found
*** ERROR: Symbol file could not be found.  Defaulted to export symbols for ntdll.dll -

我已将其报告给 Microsoft，他们正在调查此问题.

I've already reported it to Microsoft and they investigate the issue.

wntdll.pdb 现在在符号服务器上可用:

The wntdll.pdb is now available on the symbol server:
