How to: Reference Windows symbol information
The Visual Studio Profiling Tools use symbol (.pdb) files to resolve symbolic names such as function names in program binaries. You can follow these steps to automatically download and update the correct .pdb files for the version of Windows on the local computer.
This setting does not affect existing reports. Only reports created after specifying the symbol server will have the symbol information.
For more information, see Specify symbol (.pdb) and source files.
