The source code line specified by the PDB file appears to be invalid.
I have a WPF app that's using 50% CPU just sitting there, so I downloaded the trial version of ANTS 4.1 and profiled it. I pointed it to the executable in the \\bin\\debug folder and accepted all of the defaults. All of the PDB files for every EXE and DLL are in that folder, even for DLLs that I'm referencing in the app (except System.XXX). The profiler looks correct when it first comes up. When I select an area on the graph where it just sits there eating 50% CPU, it shows only the Main() method and appears to show the source code for the main app correctly.
Any idea how I can track down this error message and determine which PDB file it thinks is invalid?
It is possible that WPF is causing the high CPU use and the profiler isn't showing the issue because it's not in my code, but I want to be sure. If I do a trace, none of my code is running.
