Well, not so solved as it doesn’t work in connected mode 
We have disabled rules and adapted ones (like regular expressions for our naming conventions).
Here is the log when I start VS without connected mode :
log_slvs_without_connected_mode.txt (36.2 KB)
Then I reconnected it and everything stops working again :
log_slvs_after_putting_back_connected_mode.txt (4.9 MB)
This second log starts as the first one as I did the reconnect in the same VS session
Thanks for any help
