On Windows, 64-bit applications store some unwinding information exclusively in the executable object (.exe or .dll file). For this reason, we advise to include the executable code of your application and library during symbol upload. These files can be uploaded as stand-alone files, but you must ensure that the file base name matches the base name of the .pdb file. For example, the debug information for Editor.exe is expected to be in Editor.pdb. It is important that the name of the executable is Editor.exe in this context to pair with Editor.pdb. If the executable was uploaded as Word.exe, then you are unable to pair with Editor.pdb. It is recommended that a symbol archive is used.
