visual-studio - 当我在 Azure 中运行 Visual Studio 探查器时未找到符号

Question

我正在尝试使用 Windows Azure 中的 Visual Studio Profiler 分析我的 Windows Azure 应用程序。我按照 http://msdn.microsoft.com/en-us/library/windowsazure/hh369930.aspx#BK_ProfilingCloudService 上的说明进行操作，但是我遇到了这个问题，当我从实例下载分析报告时，它找不到符号信息，并且除了函数名称的十六进制值之外什么也没有得到。探查器输出以下错误:

等等。查看路径，这显然是在实际 Azure 实例上查找的路径(我已经通过 RDP 进入了足够多次，以识别 D:\windows 和 F:\approot 的含义)。但我正在自己的机器上查看此性能报告。那么我如何告诉探查器使用我的计算机的设置而不是 Azure 实例的设置来查找符号？

郑重声明，我正在按照链接页面中的说明进行操作，并且我已经在谷歌上进行了广泛的搜索，但一无所获。并不是说那里什么都没有，但我正在按照分析博客等中的说明进行操作，但仍然收到错误。我在 MSDN forums 上问了这个问题微软代表基本上告诉我，如果我按照说明进行操作，它肯定会起作用。

抱歉我没有早点看到这个。基本上问题是，当你的应用程序被分析时，许多二进制文件都会被生成。因此，如果没有正确的 pdb，系统无法解释函数地址，因此您会看到十六进制。您需要在 ngenbinary 存在的同一台计算机上生成 ngen pdb(请参阅 http://blogs.msdn.com/b/visualstudioalm/archive/2012/12/10/creating-ngen-pdbs-for-profiling-reports.aspx )。这应该可以处理大多数列为 *.ni.dll 的二进制文件。对于您自己的应用程序，在 Visual Studio 中设置符号位置应该足以找到您自己的应用程序的符号。希望这有帮助
