  • Profiling Type: Instrumentation

Clicked on Symbol settings and added .pdb file path. But the source code not loading. How to view source code of DLL in Instrumentation Profiler report.

In Performance Explorer window,

  1. Under profiler session - Right-click Targets and then select Add Target Binary-> select the .dll file
  2. Right click on session and select start profiling

In the New Instrumentation report I am able open source code of DLL.
