1. Download the PerfView tool (for free) from https://github.com/Microsoft/perfview/blob/master/documentation/Downloading.md
2. Once you have it open, you can see "Collect" in the menu bar at the top. Click on "Collect" and then "Run". Note this may re-launch PerfView in an elevated process, in which case you may need repeat this step in the elevated window.
3. The "Collecting ETW Data while running a command" dialog will pop up. In the Command section, put in the full path for Visual Studio. It'll look like this: "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\devenv.exe" Don't forget to add in the quotation marks!
4. Change the Current Dir field to a directory where the ETL trace files should be created.
5. Below the "Current Dir" section, you can see "Thread Time." Please make sure it's checked.
6. Ensure the "Zip" checkbox is checked.
7. Expand "Advanced Options". Ensure the "No V3.X NGEN Symbols" checkbox is checked.
8. Click "Run Command"
9. This will start an instance of Visual Studio.
