Thanks for this, Seema! I was able to get an initial report from my app, but when I try to run it a second time, I get this error in the console:

c:\Program Files\Microsoft Windows Performance Toolkit>xperf -on base

xperf: error: NT Kernel Logger: Cannot create a file when that file already exists. (0xb7).

I deleted the myprofile.etl file and got the same result.

It's not the friendliest UI, but it works. I think that you might already have xperf running, so run xperf -stop and then try again. Any interesting results?

I'm not sure what was up before, but I tried again and am not getting that error and am able to run multiple reports. However there's nothing in c:\symbols, so when I expand agcore.dll, there are no method names. I also end up with a c:\kernel.etl file after starting xperf.

to make sure that the symbols work, make sure you have done the following:

1) are running on our public RTW bits

2) have set the symbol path in your cmd shell (before launching xperfview)

3) in xperfview selected "Trace --> Load Symbols"

4) and then accepted the EULA, at least once.

does that help?

Yes, thanks, I guess I completely missed the "Load Symbols" step. This is very cool and I'll definitely use it. Though it would be awesome if this and the WPF Perf Tool were just integrated into VS somehow.

Seema, thanks for the information. I also watched your PDC session, which also gave lot of great information.

On the data shown by XPerf can you drill down deeper and help bring out what specific APIs to look and what it means. The challenge is that it is difficult to figure out a way to map that code that we have written in C# to the one that is shown in XPerf which is the agcore.dll's C++ code.
