Hi, Jan
It is a pity that the VS has only one log file(ActivityLog), and it does not provide you with the ability of looking up the custom tool load status.
So I would rather suggest you use a third-party tool-ProcessMonitor, with this tool you can monitor the action of devenv process. You could download from the link below.
If you are still not able to resolve your problem, please post your thread in the
Thanks
