Visual Studio 2013 Preview, C++：Cannot find or open the PDB file问题

编译调试Vs2013 C++ 项目时，在Output窗口能够看到有：

'xxx.exe' (Win32): Loaded 'C:\Windows\System32\ntdll.dll'. Cannot find or open the PDB file.
'xxx.exe' (Win32): Loaded 'C:\Windows\System32\kernel32.dll'. Cannot find or open the PDB file.
'xxx.exe' (Win32): Loaded 'C:\Windows\System32\KernelBase.dll'. Cannot find or open the PDB file.
'xxx.exe' (Win32): Loaded 'C:\Windows\System32\msvcp120.dll'. Cannot find or open the PDB file.
'xxx.exe' (Win32): Loaded 'C:\Windows\System32\msvcr120.dll'. Cannot find or open the PDB file.

应该是DLL文件的调试符号文件没有找到。

如图：Tools->Options: Debugging->Symbols：

勾选微软的符号服务器，并设置本地的符号文件缓存目录。

再次F5调试运行，一切OK!
