Incorrect Symbols for mscorwks.dll?

[mikemartell]

I'm using Vtune Sampling on Windows 7 for some of our performance tests. VTune reports that a lot of time is spent in the StrongNameFreeBuffer api. This is a function in mscorwks.dll. Some initial research on this indicates that VTune may not have the correct symbols for this dll, especially since our code doesn't call this function.

I'm quite sure I have installed the proper Windows symbols (Windows 7, 64 bit RTM), which were installed from here: http://www.microsoft.com/whdc/devtools/debugging/symbolpkg.mspx#d

Also found this thread that has me concerned:http://software.intel.com/en-us/articles/using-the-microsoft-symbol-server-with-the-vtunetm-performance-analyzer/

Hello,

Thanks for this valuable report.

I don't know if this is a sampling issue, andthere is no way to run Call Graph on Windows 7* to verify.

I suggest to useIntel Parallel Amplifier -run HotspotAnalysis , and verifyif there is hot function called StrongNameFreeBuff, and check call stack to know callers.

If you found that problem persists on, please send a ticket to https://premier.intel.com with test case.

Thanks, Peter

I thought time based sampling was only available in VTune. I'm happy to try Parallel Amplifier if it is known to work well with Windows 7 x64.

Please advise.

OK I installed Intel Parallel Amplifier. However, it says it doesn't work for .NET projects. Do you know if/when this tool will support .NET?
