title: C# Visual Unity standalone .exe debug symbols load issue
body: <p>I'm having a Unity project that I want to debug when launched directly from a debug release exe. Long story short - Visual shows on the breakpoint icon that symbols have not been loaded but when I check modules it shows as loaded and points to proper .pdb file.</p>
  
  <p>In Unity (2017.4.0f1) when making build "Copy PDB files", "Development Build" and "Script Debugging" options are selected. Unity makes an executable with matching .pdb files.</p>
  
  <p>In Visual (Community 2017) I attach to running process. When I move over some breakpoint, I get a warning message saying that "No symbols have been loaded for this document". However, when I go to Debug -> Windows -> Modules, my exe shows "Symbol Status" as "Symbols loaded.". The .pdb file shown there points to the right file (double checked).</p>
  
  <p>I tried setting new breakpoints but they also don't get caught. Made sure that the code actually gets run in the app and that the breakpoint indeed is not caught.</p>
